Other Contact Person Phone Information and Instructions Massachusetts General Laws chapter 152 requires all employers to provide workers' compensation for their employees. Pursuant to this statute, an employee is defined as "...every person in the service of another under any contract ohire, express or implied, oral or written." An employer is defined as "an individual, partnership, association, corporation or other legal entity, or any two or more of the foregoing engaged in a joint enterprise, and including the legal representatives of a deceased employer, or the receiver or trustee of an individual, partnership, association or other legal entity, employing employees. However the owner of a dwelling house having not more than three apartments and who resides therein, or the occupant of the dwelling house of another who employs persons to do maintenance, construction or repair work on such dwelling house or on the grounds or building appurtenant thereto shall not because of such employment be deemed to be an employer." MGL chapter 152, §25C(6) also states that "every state or local licensing agency shall withhold the issuance or renewal of a license or permit to operate a business or to construct buildings in the commonwealth for any applicant who has not produced acceptable evidence of compliance with the insurance coverage required." Additionally, MGL chapter 152, §25C(7) states "Neither the commonwealth nor any of its political subdivisions shall. enter into any contract for the performance of public work until acceptable evidence of compliance with the insurance requirements of this chapter have been presented to the contracting authority." Applicants Please fill out the workers' compensation affidavit completely, by checking the boxes that apply to your situation and, if necessary, supply sub-contractor(s) name(s), address(es) and phone number(s) along with their certificate(s) of insurance. Limited Liability Companies (LLC) or Limited Liability Partnerships (LLP) with no employees other than the members or partners, are not required to carry workers' compensation insurance.

CT Summary of Findings and Conclusions of Phase I Initial Site Investigation Hydraulic Oil Release Vehicle Maintenance Garage Massachusetts Electric Company Service Center 1101 Turnpike Street North Andover, Massachusetts Release Tracking Number 3-31085 Conditions of the Disposal Site within the vehicle maintenance garage located at the MECO facility having an address of 1101 Turnpike Street in North Andover, Massachusetts were evaluated in a manner consistent with applicable guidelines for a "Phase I - Initial Site Investigation" as presented in the Massachusetts Contingency Plan, 310 CMR 40.0000. Coneco has conducted assessment activities to evaluate soil and groundwater conditions at the Disposal Site. Investigations at the Disposal Site included a review of pertinent Site history, the advancement of two (2) Geoprobe® test borings, the installation of two (2) groundwater monitoring wells, gauging and passive recovery of NAPL, and the collection and laboratory analysis of soil and groundwater samples. Based on the information and observations described herein, the following is a summary of findings: In the Spring of 2012, MECO personnel noted that a hydraulic vehicle lift system located in the southern corner of the vehicle maintenance garage was malfunctioning. Upon inspection of the hydraulic lift system and associated 200 -gallon AST located in the southeastern portion of the garage, MECO personnel noted a drop in the hydraulic fluid level of the AST. Upon further inspection it was determined that the system had a pressure loss due to a leak somewhere in the system. MECO personnel contracted Coneco to evaluate Site conditions and determine whether there was evidence of a release of hydraulic oil to the environment as a result of identified conditions. In order to determine whether there was evidence of a release to the environment, Coneco personnel utilized an oil/water interface probe to gauge viable monitoring wells in the immediate vicinity of the lift system for the presence of NAPL, if any. Six (6) previously installed groundwater monitoring wells within the vehicle maintenance garage in the vicinity of the hydraulic lift system and four (4) groundwater monitoring wells located outside the vehicle maintenance garage were determined to be viable and were gauged. At the time of gauging activities on June 7, 2012, NAPL was not identified within the gauged wells. It was noted during the inspection that no viable monitoring wells were located in the vicinity of the lift piston and the road box of the well nearest to the piston had been damaged and could not be opened. Therefore it was determined that additional assessment activities would be warranted to determine whether a release to the environment had occurred. • On August 21 and 22, 2012, Coneco provided oversight of Geologic in the advancement of two Geoprobe® test borings, designated GP -01 and GP -02, at the Disposal Site. In addition, Geologic also repaired damaged roadboxes of all pre-existing groundwater monitoring wells. Soil boring locations were selected to determine whether evidence of a release of hydraulic oil was present in the immediate vicinity of the hydraulic lift system. The borings were NOTICE OF PHASE I INITIAL SITE INVESTIGATION AND TIER 11 CLASSIFICATION Hydraulic Oil Release Vehicle Maintenance Garage Massachusetts Electric Company Service Center 1101 Turnpike Street, North Andover, Massachusetts Release Tracking Number: 3-31085 A release of oil and/or hazardous materials has occurred at this location, which is a disposal site as defined by M.G.L. c. 21 E, § 2 and the Massachusetts Contingency Plan, 310 CMR 40.0000. To evaluate the release, a Phase I Initial Site Investigation was performed pursuant to 310 CMR 40.0480. As a result of this investigation, the site has been classified as Tier II pursuant to 310 CMR 40.0500. On September 5, 2013, the Massachusetts Electric Company d/b/a National Grid filed a Tier II Classification Submittal with the Department of Environmental Protection (MassDEP).

controls, and enclosures required for this equipment by most electrical Codes. Refer to the Codes for alternates which are allowable under certain conditions. Required Devices 1. Disconnecting Means — to disconnect motor and controller from the circuit. It must either open all ungrounded conductors and be in sight from' controller or it must lock in the open position. This design must indicate whether switch is open or closed. The disconnect must be a switch rated in horsepower or a circuit breaker of the inverse time or instantaneous trip type. The disconnect, either switch or breaker, for 600 volts or less motor circuits must be ampere rated for at least 115% of full load current. It must also be capable of interrupting stalled - rotor current. 2. Motor Feeder — Short -Circuit Protection — to protect the motor -branch -circuit conductors, the motor control apparatus, and the motors against overcurrent due to short circuits or grounds. There must be one in each ungrounded conductor. It must carry motor starting current, but not over 400% of full load current. See Tables 4 and 5 for sizing. 3. Motor Controller — to start and stop the motor. Select the controller for motor basic HP and voltage. See Tables 10, 11, 14 and 15. 4. Overload Protection — to protect the motor, control apparatus and the branch -circuit conductors against excessive heating due to motor overloads, stalled rotor and excessive cycling. Select overloads sized at 125% or less of motor full load current for motors with service factor of at least 1.15. Overload size must not exceed 115% of full load current for all other motors. Use three Running Overcurrent units. Note: Items 1 through 4 are available in a "pump panel" or combination starter. 5. Conductors supplying a single motor must have a carrying capacity not less than 125% of motor full load current. Conductors supplying more than one motor must have a carrying capacity not less than 125% of full load current rating of the highest rated motor plus the sum of the full load current ratings of the rest of the motors. Voltage drop for conductors must not exceed 3% on the branch circuit. Any conductor intended only for grounding purposes must be colored green unless it is bare. Grounded current carrying conductors must be white or natural gray color. All ungrounded conductors of the same color must connect to the same un- grounded feeder conductor. The conductors for systems of different voltages must be different colors. 6. Non -Fused Disconnect Switch — Not required if Item 1 can lock in open position or is within sight from* motor. Motors and control boxes must be grounded. "'in sight from"— must be visible and not more than 50 feet distant. MWIM Conductors Item Contained In Fusible Safety Switch or Circuit Breaker Manual or Magnetic Starter Non -Fused Disconnect Switch In Sight from Motor Electrical Supply Wiring Diagrams There are two common types of wiring diagrams. The control equipment supplier provides the standard "Wiring Diagram", showing the physical layout of components and wiring. These diagrams depict the exact connections required. Each manufacturer uses unique connection points and physical layout, so each drawing applies only to one manufacturer. "Elementary Diagrams" show the operation of a circuit in the simplest manner with no attempt to show physi- cal layout. This requires separation of the coils from their contacts.

Types most commonly used with cooling towers are described below. Type 1 General Purpose — This enclosure is intended primarily to prevent accidental contact with the control apparatus. It is suitable for general purpose application indoors under normal atmospheric condi- tions. It serves as protection against dust and indirect, light splashing. It is not dust - proof. Type 3 Dust -tight, Rain -tight and Sleet (Ice) Resistant — This enclosure is intended for use outdoors to protect the enclosed equip- ment against windblown dust and water. It is not sleet (ice) proof. This enclosure must have watertight conduit connections, mount- ing means external to the equipment cavity, and locking provision. Type 311 Rain -tight — This enclosure is intended for use outdoors to protect the enclosed equip- ment against rain. It is not dust, snow or sleet (ice) proof. When completely and properly installed, this enclosure prevents entrance of rain above the level of the lowest live part. The 311 enclosure prevents the en- trance of a rod .125" in diameter except at drain holes. Drain holes will not permit entry of a rod larger than .250" diameter. Live parts must be at least 4" from the nearest drain hole. Type 4 Water -tight — A water -tight enclosure must exclude water. It must pass a hose test. This enclosure is adequate for outdoor use on a cooling tower. It is usually a gasketed 304 stainless steel enclosure. Type 4X is a water -tight corrosion resistant enclosure that will pass a 200 -hour salt fog test. Type 7 Hazardous Locations — Class I Air Break — This enclosure meets the application re- quirements of the National Electrical Code for Class I, Group A, B, C, or D hazardous locations. These locations may contain specific types of flammable gases or vapors. Refer to the Code for more complete defini- tions of hazardous locations*. Type 7 enclo- sures are intended for indoor use but are sometimes used outdoors on cooling towers. Type 9 Hazardous Locations — Class II — This enclosure is designed for use in Class II (combustible dust), Group E, F, or G areas. Type 12 Industrial Use — This enclosure is used for industrial applications to prevent entrance of foreign materials such as dust, lint, fibers, oil seepage, or coolant seepage. 'The Code defines hazardous locations in Division land Division 2. In general, starters for either location division must be in explosion -proof enclosures. Motors for Division 1 locations must also be explosion -proof. Motors for Division 2 locations can be any enclosure, so long as motor does not employ sliding contacts, centrifugal switches or other types of switching mecha- nisms, or integral resistance devices.

Either a circuit breaker or fusible disconnect switch can serve as a disconnect means and short-circuit protec- tion. The designer must know the locked rotor code letter and full load current of the motor to properly size the short circuit protection for a given motor. These values appear on the motor name plate. Table 4 lists the locked rotor kilovolt amperes for code letters appearing on motor name plates. Table 5 lists the maximum rating or setting of motor branch circuit protective devices. Actual locked rotor current of a motor might approach 600% of full load current. However, the proper size fuse or circuit breaker will not go out on a normal motor start.

A disconnect switch for a motor load is horsepower rated. It must cant' 115% of motor full load current continuously and must be capable of interrupting motor stalled -rotor current. Many fusible switches have three horsepower ratings: standard fuse, dual element fuse, and non -fuse. See Table 8 on Page 8. Manufacturers differ slightly in horsepower rating of their switches.

Disconnect switches are available in NEMA Type 1, 3, 3R, 4, 7, 9 and 12 enclosures. Do not use plug type fuses at voltages greater than 125 volts between conductors except in a grounded neutral system with less than 150 volts from conductors to ground. Therefore, they are inappropriate for most three phase systems. Cartridge type fuses are avail- able with either renewable or non-renewable fuse elements. Good practice dictates using dual -element fuses rather than one-time fuses. Dual -element fuses interrupt higher fault currents, generate less heat in the control box, and permit use of smaller fuses for better protec- tion. In addition, if a fuse clip is loose on a one-time fuse, the case can carbonize and fail when the fuse blows. A loose clip on a dual -element fuse will cause the fuse to blow before the case can carbonize.

The thermal elements protect on overloads where inverse time tripping is desired. The magnetic trip elements in- stantly operate the breaker in case of dangerous overload or short-circuit faults. Usually circuit breakers do not operate as fast as fuses at high overcurrents, but operate faster on normal overloads. Circuit breakers offer certain advantages over fuses. They do not have to be replaced when operated. They also prevent operating the motor single phase. Circuit breakers can also be equipped for remote operation. Low voltage (600 volts and less) circuit breakers are of the air break type. Both oil and air type breakers are available for high voltage systems. Air circuit breakers are rated 15, 20, 30, 40, 50, 60, 70, 90, 100, 125, 150, 175, 200, 225, 250, 300, 350, and 400 amps. They are available in NEMA 1, 3R, 4, 7, 9 and 12 enclosures. Combination Starter A combination starter includes circuit breakers and disconnect switches as part of the motor controller. Lightning Arrester Lightning damage to motors and control equipment is usually caused by high voltage induced in the power line rather than lightning hitting the motor or control _ directly. Lightning can cause immediate failures or it can weaken insulation, causing failures at a later date. In areas where thunderstorms are frequent, it is advisable to install lightning arresters to protect motors and other Manual Controller equipment. Install arresters on the incoming side as near as practical to the piece of equipment to be protected. Connect one arrester element to each ungrounded lead. Usually, to protect a motor, it is necessary to use a secondary class arrester along with a surge -absorbing capacitor. A secondary class arrester is designed for secondary distribution systems such as those supply- ing motors. Arresters consist of a spark gap and a device to limit or quench the spark. Each manufacturer uses his own method or material to limit the spark. Lightning arresters are usually rated for the maximum phase -to -phase and phase -to -ground voltage. Motor Controller Manual Controllers consist of snap -action switch(es) and overload(s). They are available in NEMA 1, 4, 7, 9, and 12 enclosures. Standard sizes appear in Table 10. Manual controllers are available for reversing or two - speed two -winding motor control. Single phase controllers are available with selector switch and pilot light. Table 10 - Horsepower Ratings for Across -the -Line Manual Starters Magnetic Controller Types of Magnetic Starters The motor controller normally used on cooling towers is a magnetic starter. The standard magnetic starter uses a magnetic coil to close contacts and springs and/or gravity to open them. Some type of pilot device, such as a push button or float switch, actuates the magnetic coil. The main types of magnetic starters are across - the -line, reduced voltage, and reconnectable. Power company limitations on inrush current dictate the use of reduced voltage or reconnectable type starters for larger horsepower motors. Reduced starting current and torque, and increased starting time typify reduced voltage and reconnectable type starters. Therefore, the designer must allow sufficient torque to accelerate the load and to keep starting time short enough to avoid overheating the motor.

The pilot device energizes the magnetic coil of a primary resistance starter, connect- ing the motor to the line through resistors. The resis- tors normally limit the motor voltage to 65% or 80% of normal voltage. A timer, energized at the same time as the motor, times out and picks up the run contactor which in turn connects the motor directly across the line at a predetermined time interval. This type of starter limits the inrush current, gives smooth motor and load acceleration, and provides a higher starting cycle. Disadvantages of this starter are the physical size of the starter and resistors and the power loss in the resistors. Primary resistance type starters are called "close transition starting units." —11— 2 Wire Control STOP START 1 2 .L 3 L1 F L2 L3 --� TR OL c 200 Typical Wiring Diagram of — Primary Resistance Starter Q 100 C� JH 0 Auto -transformer Starters: Auto -transformers reduce the starting voltage in this type of starter. The advantages of this type of starter are: The starter contains several voltage taps. The de- signer may select the correct reduced voltage for each application. For motors up through 50 HP, 65% and 80% voltage taps are included. For larger horsepower motors, 50%, 65% and 80% voltage taps are included. The transformer ratio reduces the line current for a given torque. Both open -circuit transition and closed-circuit transition auto -transformer starters are available. Open -circuit transition: A timer and the motor are energized simultaneously through the transformer tap.

Disadvantages of this type starter are: high cost, low power factor, complete loss of power when the motor is disconnected from the auto -transformer, and high inrush current when the motor is connected across the line. Closed-circuit transition: Three transformers are first connected in wye and the motor is energized through the transformer taps. After a timed interval, the wye connections open, leaving the transformer secon- dary winding in series with the motor. The motor is then connected directly across the line and the trans- formers are disconnected. Full voltage induces a lower current peak and complete loss of power does not occur. —12— r 12— L1 L2 L3 L1 19 L3 _' _ 2 Wire Control - Use Dotted Lines and �rStart7 Remove Jumper 3 to 4 Ston r Typical Wiring Diagram of Auto -Transformer Starter with Open -Circuit Transition -0 600 co 0 —J 500 a LL -p li 400 cc 0 co 0 300 c, m 300 o CURRENT CURRENT 200 c 200 aa) Cr loo U TORQUE _ --------------� c_ J 9 m Q 100 0 TORQUE �o 0 10 20 30 40 50 60 70 80 90 100 ------------- J H 0 0 10 20 30 40 50 60 70 80 90 100 % SYNCHRONOUS SPEED I --� �– — — — 2 Wire Control Stop Start TR1 F TR1 TF1 imI m miw OL Typical Wiring Diagram of Auto -Transformer Starter with Closed -Circuit Transition —13— Typical Current and Voltage Curves with 65% Voltage on First Step for Design `B" Induction Motor OL -0 600 W 0 J 500 a LL 400 cc 0 c, m 300 CURRENT t C 200 aa) Cr loo TORQUE _ --------------� c_ J 9 0 0 10 20 30 40 50 60 70 80 90 100 % SYNCHRONOUS SPEED Typical Current and Voltage Curves with 65% Voltage on First Step for Design `B" Induction Motor Reconnectable Starters Part -winding Starters: Reconnectable starters can be either part -winding, or star delta type. Part -winding starters require that the motor stator winding must be made up of two or more circuits connected in parallel for normal operation. Standard 230/460 volt motors, 15 horsepower and larger, are generally suitable for part -winding starting at the lower voltage. Check first with the motor manufacturer. In the first step of part -winding starting, half the motor winding and a timer are energized. At a predetermined time interval (usually one second), the second half of the motor winding is connected in parallel with the first half. The locked rotor current on the first step is approximately 60% to 65% of full locked rotor amps. The locked rotor torque is approximately 46% to 49% of full locked rotor torque. Part -winding starting is primarily used to allow the voltage regulator to adjust, preventing excessive line voltage reduction. With this method, a dip appears in the torque curve at half speed. Overloads and fuses for use with part -winding starters should be sized for half the motor full load current and placed in each of the six lines to the motor. 2 Wire Control ~TR Stop SOL L1 S L2 S TR F L3 Fuse S S S TF F F VT3 OL OL 8 T9 -0 600 ca 0 -� 500 ' a LL aoo C O CURRENT C o 300 - I Typical Wiring Diagram a) of Part -Winding Starting —` zoo UW I C Cr 100 TOQUE J Star -delta Starters: The motor must be wired for running delta, with enough leads brought out to con- nect the motor for a star (or wye) start.

In the closed transition type, the motor remains con- nected to the line through resistors during the connec- tion change from star to delta. Special Features Single -Speed Motor Starters Auxiliary Contacts: Auxiliary contacts, sometimes called interlocks, are mechanically connected to the starter so that energizing the starter coil opens the contacts (N.C.) or closes the contacts (N.O.). Most starters come with one auxiliary contact. This contact appears in the holding circuit with three -wire control or it can control operation of other equipment with two - wire control. Additional contacts (1 to 4, depending on starter) are available factory installed or for field installation.

They are wired into the circuits at the factory. Pilot lights are normally wired in parallel with the coils whose operation they indicate (see wiring diagram on page 24). Control Transformer: Personnel safety sometimes dictates low voltage control circuits. To accomplish this, the control circuit can be wired for connection to a separate power source, or a control circuit transformer can be a part of the starter to provide a 115 -volt control circuit voltage. Some control circuit transformers have enough capacity for a 100 -watt work lamp. A fuse in the secondary circuit provides short circuit protection for the transformer and control circuit. The wiring diagram on page 30 shows how to wire a control trans- former into the controls system. Time Delay Contacts or Relays: Reversing a fan without a time delay imposes a heavy shock load on the drive. Marley recommends a two -minute time delay when reversing so •that the fan can slow down to windmilling speed before it actually reverses (see wiring diagram on page 24). — 15 — The timing head used by some manufacturers employs the starter coil and does not require a coil of its own (see page 24). Other manufacturers use a timer with its own coil. On page 24, these timer coils must be in parallel with the proper starter coil (forward timer coil in parallel with forward starter coil, etc.). Timers are available with two different types of contact operation: Instantaneous operation on energization with time delay operation on de-energization. Time delay operation on energization with instantane- ous operation on de-energization. Additional contacts without time delay are available. On multi -fan towers, it is sometimes desirable to prevent more than one fan starting at the same time. Interlocks in the motor starters and time delay relays can accomplish this goal. However, some means is necessary to permit removing a fan from service for maintenance while the rest of the fans are operating. A sequence alternator can accomplish the same thing if only one fan is required at a time and alternating fans is desirable. Multi -Speed Starters Mufti -speed motor magnetic starters are available with the same features listed for single -speed motor start- ers. The following additional features are also avail- able: Compelling Relay: A compelling relay connected in a mufti -speed starter allows the motor to start only at low speed. Any higher speed is available only after a low -speed start. Pressing any push button except low speed will not start the motor. This arrangement insures that the motor will always first move the load at low speed. The motor can only change from a higher to a lower speed after the stop button is pressed. Accelerating Relays: A multi -speed starter equipped with accelerating relays starts the motor at low speed and automatically accelerates it through successive steps until the motor reaches the selected speed. The operator selects the motor speed by pressing the proper start button. Definite time intervals must elapse between each speed change. Individual timing relays control each interval, and all are adjust- able. The motor can only change from a higher to a lower speed after the stop button is pressed. Decelerating Relays: These are similar to acceler- ating relays except that they prevent immediate reduc- tion from a higher to a lower speed. Both the driven machinery and the motors suffer tremendous strains when the motor changes to a lower speed without allowing the motor to adjust to the lower speed. Marley recommends a 20 -second time delay before energizing a lower speed winding. - Control of Magnetic Starters Three -Wire (Push Button) Control The controls for magnetic starters are either three -wire or two -wire controls. Three -wire control is manual control. An operator must push a button to start the motor. Starters with three -wire control provide "under voltage protection" for a motor. When the motor stops because of a voltage failure, it will not restart until the start button is pushed. Separate push buttons select each speed and stop. Push buttons serve as momentary contact devices. Once the push button energizes the starter coil, the circuit bypasses the start button. The circuit may include any number of push buttons. Start buttons are in parallel and stop buttons are in series. Standard - duty push buttons are available with either normally open or normally closed contacts. Heavy-duty push buttons have both normally open and normally closed contacts. Push buttons are also available with lock -out devices, built-in lights, and different actuators and actuator guards. Indicator lights are available with or without attached transformer. Push buttons are available in NEMA Type 1, 4, 7, 9, and 12 enclosures. Selector switches can serve the same function as push buttons. Since a selector switch is a maintained contact device, only one can be used to energize a starter wired for three -wire control. Any number can be used to de -energize a starter. Hand key or coil operated selector switches are available with two or three contact positions. Two -Wire Control The starter must use three -wire control to provide both manual and automatic starter control. Where only automatic control is required, the magnetic starter is wired for two -wire control. Starters with two -wire control provide "under voltage release", which discon- nects the motor from the line if the voltage gets too low. However, the motor automatically goes back on the line when the voltage comes back up. Limit switches, pressure switches, temperature switches, and relays used with two -wire magnetic starter control offer automatic motor control. —16— Variation in Starter Overload Tripping Current with Ambient Temperatures No MEMMINIMMIMMEME MEN MEN IMMINIMMEMM IMMINIMEMER MEN MEN MEN MEN MINIMMEEMS OEM ONE.

The starting time is adjustable from one second up to 24 seconds or more, depending on the manufac- turer. The advantage of soft start is the reduced starting torque and shock on the fan drive. An energy saving feature in these controllers reduces the voltage to the motor at partial loads. This reduces the losses in the motor by reducing the magnetic flux density. It also improves the power factor. The cost of these controllers is approximately $30 per horsepower in a NEMA 12 enclosure. A soft start controller is usually installed between the "across -the -line" starter and the motor. Variable Frequency Drive The past few years have seen considerable develop- ment of variable frequency controls that permit operat- ing standard, three-phase, squirrel cage induction motors as variable speed motors. These controllers convert one or three-phase a.c. power to d.c., then re- convert it to three-phase variable voltage and fre- quency power. They try to maintain constant volts per cycle so that the motor torque remains constant at all speeds. Motor cooling becomes less effective at low speeds, so some applications may require reduced load torque at lower speeds. However, this limitation. does not apply to fan and pump applications. Diode or SCR bridges convert the a.c. power to d.c. The drive also controls the voltage by adjusting the firing point of the SCR's. Some users have reported "-V SCR's introduce noise back in the line, causing )blems with computers. An isolation transformer and/or suppression equipment either at the computer or at the variable frequency drive may be necessary if this occurs. Diode bridges, on the other hand, cannot regenerate power back to the a.c. line (regenerative braking). Manufacturers who use diode bridges instead of SCR's to convert to d.c. usually guarantee that they will not put noise back to the line. Since the d.c. from a diode bridge is at constant voltage, it is necessary to add an SCR or transistor to the output to control the voltage to some inverters. The device that changes d.c. back to variable fre- quency a.c. is called an inverter. Three basic inverter designs are common: (1) Six steps voltage inverter (VSI). (2) Six steps current inverter (CSI). (3) Pulse width modulating inverter (PWM). This inverter uses constant voltage d.c. Most variable frequency drives in the 1 to 200 HP range use voltage source inverters (VSI). Many 1 to 20 units are the (PWM) type. The losses at full load in power source are about 3% for the VSI type and 5% for the PWM type. Motor losses with a PWM inverter are less than with a VSI inverter since the power supplied is closer to a sine wave. In addition, the motor losses on a VSI control increase 10% to 20% because the input is a square wave rather than a sine wave source. The temperature rise in a motor varies almost directly with the losses. As an example of these two effects, an 80°C rise 90% efficient motor would have a 96°C rise and be 88% efficient when operating on a square wave. Because of this effect, some motor manufacturers recommend using a high efficiency 1.15 service factor motor with an inverter power source. Motor starting time and torque and decelerating time and torque are adjustable with a variable frequency controller. The cost per horsepower of variable fre- quency controls decreases as the horsepower capacity of the control increases. Cost and performance of variable frequency drives will continue to improve as development continues and the devices gain popular- ity. Base unit prices do not include a temperature controller, start-up engineer, critical speed lockout, safety disconnect or motor starters to permit alternate operation direct across -the -line. The designer must consider several other restrictions when specifying a variable frequency controller for a water cooling tower. Splash lubricated gear reduction units require a minimum operating speed for adequate lubrication. This minimum input speed varies with the gear unit design, and is between 440 and 750 RPM on a Marley Geareducerm. The inverter controls must prevent motor operation below the minimum speed. Also, some tower components may have a natural frequency within the range of operating speeds of a variable frequency motor drive. If the equipment operates for any significant time at the critical speed, a catastrophic failure could occur. Therefore, the inverter controls must prevent operation at or near a critical frequency. Most variable frequency control manufac- turers offer field -installed kits to "lock out" a 4 Hz band around a critical frequency. —21— Programmable It has always been possible to reduce the cooling effect on a multi -fan tower by turning off fans or reducing fan speed with a multi -speed motor. Either an operator changed speeds manually or automatic controls with thermostats changed the speed using relays and timers. A thermostat normally controlled each speed change on each motor. The thermostats were all set at differ- ent temperatures to prevent changing speed on more than one fan at a time. By adding timers or a multi - circuit timer, it was possible to use one thermostat (temperature) to increase speed and another thermo- stat (temperature) to decrease speed of all fans as required. Programmable controllers are now available to in- crease or decrease fan speed; wait for the water Controllers temperature to stabilize; then change another fan speed. These controls can also prevent motor over- heating from excessive cycling. They still require two thermostats, one to increase fan speed and one to decrease fan speed. A dead band between the two temperatures allows operation with no speed change required. Programmable controllers replace only the control of the magnetic motor starters, not the magnetic starters themselves. The cost of a programmable controller depends on the number of inputs and outputs required. An input could be a thermostat or selector switch, for example. Switching a motor speed would be considered an output. For example, 4 two -speed motors would require eight outputs to get eight changes in tower air rate. —22— Purchasing Information The customer should specify the following information en purchasing individual items of control equipment.

BE SURE TO TURN OFF POWER SUPPLYING ELECTRICAL EQUIPMENT BEFORE WORKING ON IT! �j Safety The control system by Marley uses all UL listed components installed in accordance with the National Electrical Code. The location of the cooling tower and field installation of the control system can affect the safety of those responsible for installing, operating or maintaining the tower and controls. However, since Marley does not control the tower location, or field installation, we cannot be responsible for addressing safety issues that are affected by these items. The following safety issues should be addressed by those respon- sible for installation, maintenance or repair of the tower and controls: • Access to and from the control panel (including the disconnect switch). • Proper grounding of electrical control circuits. • Sizing and protection of branch circuits feeding the control panel. • Qualification of persons who will install, maintain and service the electrical equipment. These are only some of the safety issues that may arise in the design and installation process. Marley strongly recommends that you consult a safety engineer to be sure that all safety considerations have been addressed. Other safety issues are addressed in literature supplied with your tower. You should closely review those materials prior to installing, maintaining or repairing your tower. 3 Factory Installation The control panel bolts directly to the tower with spacers or to a bracket attached to the tower. The thermostat is bolted to the tower casing adjacent to the cold water basin depressed section. The capillary runs through a bushing in the tower casing and the bulb is installed vertically in a holder near the outlet for proper temperature measurement. The holder is "glued" to the cold water basin floor with a layer of sealer applied to it's bottom flange and the bushing through which the capillary passes is filled with sealer to protect the capillary. A vibration limitswitch is mounted near the Geareducero on larger towers and near the motor on belt driven towers, Liquid tight flexible metal conduit connects all points which are to be wired—motor, control panel, thermostat and vibration limit switch, if required. The conduit is installed with associated cou- plings, connectors and fittings approved forthis conduit and is also supported by conduit clamps as required by code. After the completion of the conduit installation, the wiring is pulled through the conduit to each component. Pulling type fittings are used to provide access for pulling the wire and meeting the N.E.C. requirement for maximum number of bends allowed in each conduitrun. All wire ends are tagged for identification and connec- tions at each end are made at terminal blocks or by terminal connectors with fasteners. 4 C Factory Installation Overload thermal units are selected based upon the full -load current as read from the motor nameplate. Fuses are selected based upon the motor voltage and full -load current (high speed current on two speed motors) as listed in the National Electric Code. The overload thermal units are installed into the motor starter and the time delayfuses are installed into the fuse clipswith the grooved end on the bottom. (A bar in the fuse clip requires the use of a time delay fuse which has a groove to fit over the bar.) The time delay relay on the two speed control panel is adjusted for a 30 second or more delay and the thermostats are preset as follows: One speed Cut in temperature 85° F Cut out temperature 80° F Two speed 72° F The completed factory installation is tested by cycling the fan off and on both manually and automatically with the control panel switches and the thermostat respectively 5 Field Connection L Note The factory installation by Marley has been performed in accor- dance with the National Electrical Code using UL Listed compo- nents. All installation and wiring performed after leaving the factory must be performed in accordance with the latest revision of the National Electrical Code and any local codes to insure safe operation. � Warning 2 The Marley Basic Control System has been factory installed to the fullest extent possible. Some equipment selections and options require the installation be completed in the field. The following information is provided as an overview ofthe field installation forthe various options. Please referto the drawings supplied with the tower for more detailed instructions to complete the installation. HAZARD OF ELECTRICAL SHOCK OR BURN.

Be sure to maintain adequate differential between the cut -in and cut-out settings or excessive cycling of the fan motor may occur and shorten equip- ment life. 12 Field Connection Two Speed Option 1. The installation is the same as for the single speed except direction of rotation must be checked on both speeds. If motor runs _forward on one speed and backwards on the other, reverse any .two wires at the motor starter connections for the speed that runs backwards. 2. The temperature switch on two speed systems has a differential that is preset bythe manufacturer. The temperature setting is all that needs to be checked on this system. Remember the differential is all above the temperature setting on the two stage switch. Referto Figure 2 on page 19. 3. Setthe pneumatictime delay relay for 30 seconds minimum time delay when switching from high to low speed. The time delay is adjusted by turning the air bleed screw on the top front side of the relay. 13 Control System Operation The Basic Control System allows the operation of the cooling tower in either the manual or automatic mode. Automatic operation starts, stops and/or changes speed of the cooling tower fan motor based on cold water temperature. Cold water temperature ob- tained from an operating cooling tower will vary with the heat load, air wet -bulb temperature, water flow rate and air flow rate. Note When operating in the automatic mode care must betaken not to exceed a total acceleration time of 30 seconds per hour on the fan motor. Excessive cycling of the motor may reduce the life of the motor starter, motor and driven mechanical equipment. Note When operating in sub. freezing weather, the opportunity exists for ice to form in the colder regions of the cooling tower. Your primary concern is to prevent the formation of destructive ice in the cooling tower fill. Care must be taken not to allow temperature control settings below 400 for automatic operation or unattended manual operation in sub -freezing weather. Your understanding of cold weather operation will be enhanced if you read Marley Technical Report #H-003 "Operating Cooling Towers in Freezing Weather" and your cooling tower's `Installation, Operation, and Mainte- nance Instructions" manual. Failure to comply with these instruc- tions will result in damage to your tower. Single Speed Manual Operation 1.

BE SURE TO TURN OFF POWER SUPPLYING ELECTRICAL EQUIPMENT BEFORE WORKING ON IT. Contacts The contacts inside the electromagnetic contactor, which con- nect the motor to the power source are the only components that experience wear in normal service requiring periodic replace- ment. Two years is not considered unusual forthe service life of silver - alloy contacts. All service worksuch as replacement of the contacts should be performed by a qualified electrician. A Note Contacts are replaced many times when this expense is not necessary. Contacts are not harmed by discoloration of the surface or slight pitting. We do not recommend filing them as dressing only removes contact material which is wasteful. Re- placement is necessary only when the contact has worn thin. Coils Coils have an indefinite service life under normal operating condi- tions. Coils generally operate improperly or fail because of unac- ceptable voltage or from mechanical abuse. 21 System Maintenance Fuses and Themnal Overloads The fuses and overloads installed by Marley are the maximum size allowed by the National Electrical Code. If a fuse blows repeatedly check the system for a short circuit or ground fault condition. The thermal overload units are the melting alloy type and are reset by depressing the reset button. Overloads trip most frequently be- cause of mechanical overloads or frequent cycling of the fan motor. Visual Visual inspections should be conducted during installation and at six month intervals. Check all connections fortightness. Vibration or improper installation can cause loose connections resulting in increased resistance to current flow. We recommend the use of copper wire only. During the visual inspection we recommend the use of compressed air and brushes to clean dirt from magnetic pole faces and contacts. 22 Single Speed Wiring Details — 3 Phase INCOMING POWER I Li L2 L3 TERMINAL BLOCK GREEN NORMALLY CLOSED VIBRATION SWITCH (OR JUMPER AT RED. 5 TO 7) RED NORMALLY OPEN CONTACTS FOR CUSTOMER SUPPLIED OVERLOAD TRIP ALARM (OPTIONAL) RANGE ADJUSTMENT SCREW ADJUSTMENT SCREW SENSING BULB IF MOTOR RUNS BACKWARDS SWITCH ANY TWO WIRES u Note: Terminal block numbers are shown out 2 of order.

Power disconnected. • Fuses Blown. • Overloads tripped. • Vibration switch tripped or jumper wire missing Nuisance Tripping • Sustained overload. Check for equipment grounds or shorts. • Check motor winding resistance, fan pitch, drive reduction ratios, air flow restrictions on tower fans and tower loading, • Loose connections. • Excessive motor cycling. Increase temperature differential until 30 seconds maximum acceleration time per hour is achieved on the fan motor. Contact Chatter • Broken shading coil • Low voltage. • Intermittent supply voltage. Contact Welding • Abnormal inrush of current, Check for grounds, shorts or excessive overload currents. • Insufficient tip pressure.

Marley's SystemConnect'"variety of piping systems accommodates your design intentions to make your layout of the NC Series both expedient and economical. o Single or dual hot water inlet connections • Side inlet, bottom inlet or top inlet connections o Side or bottom cold water outlet connections o A variety of makeup, overflow and drain options All piping from the single inlet connection to the distribu- tion basins is part of the tower package. Installation and design costs are reduced and the need for extra piping and supports are eliminated. The single bottom inlet connection is perfect for multicell applications, keeping all the inlet piping below the tower. Unless otherwise specified, single -cell towers normally have a side -outlet suction appropriate for the design water flow rate—see page 7. This usually assures the lowest possible installed tower elevation. Side -suction connection pipes extend roughly 3" outside the basin, and are beveled for weld connection and also grooved for a mechanical coupling. Outlet piping can be kept below the cold water basin level by choosing either a depressed sump or a bottom outlet connection in lieu of the side suction. Bottom outlets conform to standard class 125 ANSI pipe flange specifica- tions. All outlet arrangements include easily removable debris screens. Depressed sumps are made of inert FRP or heavy - gauge welded stainless steel. Unless otherwise specified towers with galvanized steel collection basins use FRP sumps and towers with stainless steel basins use stainless sumps. Multicell towers, intended to operate together as a common unit, are joined by steel flumes between the collection basins. These flumes equalize the operating water level between basins and also provide a flow pas- sage from cells not equipped with outlets—eliminating the need to specify an outlet for each cell of a multicell tower. Select the number of outlets required to maintain a maxi- mum flow of 1,500 GPM through each flume for NC1100 through NC6100, and 2,125 GPM for NC7100. The flow through flumes of successive cells without outlets is cumulative. If each cell is to be equipped with an outlet, side -suctions can be used at both ends of multicell towers, but not on intermediate cells of installations over two cells. For direct outlet from each cell of towers with three or more cells, use either the sump or bottom outlet arrangements. The best choice for a tower used with a remote or indoor storage tank (see page 8) or on a concrete cold water basin is usually a bottom outlet, with or without screen. A side -suction equipped tower can be installed on a flat concrete slab if a side drain and overflow are also specified. Consult your Marley application engineer for complete information. Makeup The amount of water constantly evaporated from a cooling tower varies directly with the heat load applied. In addition to evaporation, water is normally lost to the blow - down (bleed -off) necessary to maintain contaminant concentration at an acceptable level in the circulating water system. Marley provides one or more float -operated, mechanical valves to automatically replenish this lost water. The tables below, calculated for a concentration of 3 times normal, indicate the rate of water loss—and the size of valve(s) required. If your installation's cold water basin will drain by gravity to a remote storage tank—or if you plan a separate means of controlling makeup water—we offer a price reduction for deleting the Marley -supplied valve(s).

SUPPORT Bottom Outlet Connection Freeze Prevention When the ambient air temperature falls below 32°F, the water in a cooling tower can freeze. "Marley Technical Report #H-003" Operating Cooling Towers in Freezing Weather describes how to prevent freezing during opera- tion. Ask your Marley application engineer for a copy. During shutdowns, water collects in the cold water basin and may freeze solid. You can prevent freezing by adding heat to the water left in the tower. Or, you can drain the tower and all exposed pipework at shutdown. Electric Basin Heaters Marley offers an automatic basin heater system, con- sisting of these components: Stainless steel electric immersion heater(s). —Threaded couplings are provided in the side of the collection basin. NEMA 4 enclosure containing these components: —Magnetic contactor to energize heater. —Transformer to convert power supply to 24 volts for control circuit. —Solid state circuit board for temperature and low- water cutoff. Enclosure may be mounted on the side of the tower. Control probe in collection basin to monitor water temperature and water level. These components are normally shipped separately for installation at the job site by others. When purchased in conjunction with the Marley Control System option, they are factory installed and tested. Any exposed piping that is still filled with water at shutdown—including the makeup water line—should be electrically traced and insulated (by others). Steam Jet Basin Heaters Penberthy Houdaille bronze steam jet heaters (1/4" to 3/4") are available from Marley for freeze protection (instal- lation by others). Injectors install in a coupling provided in the side of the collection basin. Live steam, as required, is injected directly into the water. Condensed steam adds water to the basin, and the excess will exit the overflow of the tower. Indoor Tank In this type of system, water flows from an indoor tank, through the load system, and back to the tower, where it is cooled. The cooled water flows by gravity from the tower to the tank located in a heated space. At shutdown, all exposed water drains into the tank, where it is safe from freezing. The following table lists typical drain -down capacities for all NC Series tower models. Although Marley does not produce tanks, many of our representatives offer tanks supplied by reputable manufacturers. The amount of water needed to successfully operate the system depends on the tower size and GPM and on the volume of water contained in the piping system to and from the tower. You must select a tank large enough to contain those combined volumes—plus a level sufficient to main- tain a flooded suction on your pump. Control makeup water according to the level where the tank stabilizes during operation.

Operating and Environmental Awareness Sound Control Sound produced by a NC Series tower operating in an unobstructed environmentwill meet all butthe most restric- tive noise limitations—and will react favorably to natural attenuation. Where the tower has been sized to operate within an enclosure, the enclosure itself will have a damp- ing effect on sound. Sound also declines with distance—by about 5 dBA each time the distance doubles. Where noise at a critical point is likely to exceed an acceptable limit, several options are available—listed below in ascending order of cost impact: In many cases, noise concerns are limited to night- time, when ambient noise levels are lower and neighbors are trying to sleep. You can usually resolve these situations by using two -speed motors in either 1800/900 or 1800/1200 RPM configuration—operat- ing the fans at reduced speed without cycling "after hours". The natural nighttime reduction in wet -bulb temperature makes this a very feasible solution in most areas of the world, but the need to avoid cycling may cause the cold water temperature to vary signif- icantly. The Marley Variable Frequency Drive automatically minimize the tower's noise level during periods of reduced load and / or reduced ambient temperature without sacrificing the system's ability to maintain a constant cold water temperature. This is a relatively inexpensive solution, and can pay for itself quickly in reduced energy costs. Where noise is a concern at all times—for example, near a hospital—the best solution is to oversize the tower so it can operate continuously at reduced (1200 or 900 RPM) motor speed. Typical sound reductions are 7 dBA at 2/3 fan speed or 10 dBA at 1/2 fan speed. Extreme cases may require inlet and discharge sound attenuator sections, however, the static pressure loss imposed by attenuators may necessitate an increase in tower size. This is the least desirable approach because of the significant cost impact—and because of the obstruction to normal maintenance proce- dures. Your Marley application engineerwill help you meet your sound requirements. Enclosures Occasionally, cooling towers are located inside archi- tectural enclosures for aesthetic reasons. Although NC Series towers adapt well to enclosures, the designer must realize the potential impact of a poorly arranged enclosure on the tower's performance and operation. The designer must take care to provide generous air inlet paths, and the tower's fan cylinder discharge height should not be lower than the elevation of the top of the enclosure. Obtain a copy of "Marley Technical Report #H-004" External Influences on Cooling Tower Performance from your Marley appli- cation engineer. As suggested in the aforementioned Technical Report, it may also be advisable to specify a design wet -bulb temperature 1 °F higher than normal to compensate for potential recirculation initiated by the enclosure. You'll benefit from discussing your project with your Marley appli- cation engineer. System Cleanliness Cooling towers are very effective air washers. Atmo- spheric dust able to pass through the relatively small louver openings will enter the circulating water system. Increased concentrations can intensify system maintenance by clog- ging screens and strainers—and smaller particulates can coat system heat transfer surfaces. In areas of low flow velocity—such as the cold water basin—sedimentary de- posits can provide a breeding ground for bacteria. In areas prone to dust and sedimentation, you should consider installing some means for keeping the cold water basin clean. Typical devices include side stream filters and a variety of filtration media. Water Treatment In order to control the inevitable buildup of dissolved solids as water evaporates from the cooling tower, you should plan to develop a consistent, effective program of water treatment. The program must control corrosion, scale buildup and accumulation of biological contaminants. An acceptable water treatment program must be com- patible with the variety of materials incorporated into a cooling tower, ideally the pH of the circulating water should fall between 6.5 and 8.0. Batch feeding of chemicals directly into the cooling tower is not a good practice, since localized damage to the tower is possible. Additional water quality requirements appear in the NC and NC Modular Owner's Manual which accompanies the tower. For complete water treatment recommendations, con- sult a competent, qualified water treatment supplier. Most systems can be successfully treated with a MARLEYOZONET" System. This removes the requirement for other chemical feed systems and provides significant watersavings. Forcomplete information, contact your local Marley application engineer.

Additional Information Typical Applications You can use the NC Series tower in normal applications requiring cold water for the dissipation of heat. This in- cludes condenser water cooling for air conditioning, refrigeration, and thermal storage systems, as well as their utilization for Free Cooling in all of those systems. They are also used in the cooling of jacket water for engines and air compressors, and are widely applied to dissipate waste heat in a variety of industrial and manufacturing processes. Being constructed of stainless steel and other inert materials, the NC Diamond Series can be confidently applied in unusually corrosive processes and operating environments. However, no single product line can answer all problems, and selective judgement should be exercised in the following situations Applications Requiring Alternative Cooling Tower Selections Certain types of applications are incompatible with any cooling tower with PVC film -type fill—whether NC Series or a competitive tower of similar manufacture. PVC is subject to distortion in high water temperatures, and the narrow passages typical of film -type fill are easily clogged by turbid or debris -laden water. Some of the applications, which call for alternative tower designs are: o Water temperatures exceeding 125°F—willadverse- ly affect the service life and performance of normal PVC fill. o Ethylene glycol content—can plug fill passages as slime and algae accumulate to feed on the available organic materials. o Fatty acid content—found in processes such as soap and detergent manufacturing and some food pro- cessing, fatty acids pose a serious threat for plugging fill passages. o Particulate carry over—often found in steel mills and cement plants, can both cause fill plugging, and can build up to potentially damaging levels on tower struc- ture. a Pulp carry over—typical of the paper industry and food processing where vacuum pumps or barometric condensers are used. Causes fill plugging which may be intensified by algae.
