INSTALLATION
1. SAFETY PRECAUTIONS
Read this manual thoroughly, paying special attention to the sections that apply to you, before working with the UPS. Retain this manual for
use by installing personnel.
Under typical operation and with all UPS doors closed, only normal safety precautions are necessary. The area around the UPS system should be kept free from puddles of water, excess moisture, or debris.
Special safety precautions are required for procedures involving handling, installation, and maintenance of the UPS system or the battery. Observe all safety precautio n s in this manual before handling or installing the UPS system. Observe all precau t ion s in the Operation and Maintenance Manual, before and during performance of all maintenance proced ures. Observe all battery safe ty precautions before working on or near the battery.
This equipment contains several circuits that are energized with high voltage. Only test
equipment designated for troubleshooting should be used. This is particularly true for oscilloscopes. Always check with an AC and DC voltmeter to ensure safety before making contact or using tools. Even when the power is turned Off, dangerously high potentials may exist at the capacitor banks and at the batteries.
when performing the actions described by that text.
A Danger signals immediate hazards resulting in severe personal injury or death. For example:
DANGER
A DANGER SIGNALS IMMEDIATE HAZARDS WHICH WILL RESULT IN SEVERE PERSONAL INJURY OR DEATH.
A Warning signals the presence of a possible serious, life-threatening condition. For example:
WARNING
LETHAL VOLTAGES MAY BE PRESENT WITHIN THIS UNIT EVEN WHEN IT IS APPARENTLY NOT OPERATING. OBSERVE ALL CAUTIONS AND WARNINGS IN THIS MANUAL. FAILURE TO DO SO COULD RESULT I N SERIOUS INJURY OR DEATH. D O NOT WO RK ON O R OPERATE THIS EQUIPMENT UNLESS YOU ARE FULLY QUALIFIED TO DO SO!! NEVER WORK ALONE.
A Caution indicates a condition that could seriously damage equipment and possibly injure personnel. For example:
ONLY qualified service personnel should perform maintenance on the UPS system.
When performing maintenance with any part of the equipment under power, service personnel and test equipment should be standing on rubber mats. The service personnel should wear insulat ing shoes for isolation from direct contact with the floor (earth ground).
Unless all power is removed from the equipment, one person should never work alone. A second person should be standing by to assist and summon help in case an accident should occur.
Four types of messages are used throughout the manual to stress important text. Carefully read the text below each Danger, Warning, Caution, and Note and use professional sk ills and prudent care
Liebert Series 600T UPS, 65-225 kVA, Single Module 1
CAUTION
Extreme care is necessary when removing shoring braces. Do not strike the cabinet with hammers or other tools.
A Note emphasizes important text. If the note is not followed, equipment could be damaged or may not operate properly. For example:
NOTE
If the UPS system has a blown fuse, the cause should be determined before you replace the fuse. Contact Liebert Global Services.
2. INSTALLATION CONSIDERATIONS
Install your Series 600T UPS in accordance with the submittal drawing package and the following procedures.
A Liebert authorized representative must perform the initial system check-out and start­up to ensure prop er sy st e m ope rat ion . Equipment warranties will be voided unless system start-up is performed by a Liebert authorized representative. Contact your local Liebert sales representative or Liebert Global Services at 1-800-543-2378 to arrange for system start-up.
CAUTION
Read this manual thoroughly before attempting to wire or operate the unit. Improper installation is the most significant cause of UPS start-up problems.
Do not install this equipment near gas or electric heaters. It is preferable to install the UPS in a restricted location to prevent access by unauthorized personnel.
1. Proper planning will speed unloading,
location, and connection of the UPS. Refer to Figures 11 through 58 and the Site Planning Data (Appendix A).
2. Be certain that the floor at the final equipment location and along the route (inside the facility) to the installation site can support the cabinet weight an d the weight of any material handling equipment. The UPS modules can weigh up to two tons. The battery cabinets weigh between 2300 and 5000 pounds each.
4. Refer to information later in this manual regarding the optional Battery Cabinet(s), Maintenance Bypass Cabinets, Panelboards and Switchboa rds. Observe
all battery safety precautions when working on or near the battery.
5. Use the shortest output distribution cable
runs possible, consistent with logical equipment arrangements and with allowances for future additions if planned.
6. Recommended ambient operating temperature is 25C (77F). Relative humidity must be less than 95%, non­condensing. Note that room ventilation is necessary, but air conditioning may not be required. Maximum ambient operating temperature for the UPS and switchgea r is 40C (104F) without derating. The batteries should not exceed 25 C (77F). At elevations above 4,000 feet (1219 meters) temperature derating may be required for full power output (consult your Liebert sales representative).
7. Even though your Li ebert UPS unit is 92.5 to 94% efficient, the heat output is substantial. For more specific information, see the Site Planning Data (Appendix A). Be sure environmental conditioning systems can accommodate this BTU load, even during utility outages.
8. The installer should attempt to balance the load between the three out put phases . The UPS will operate safely with an unbal­anced load, but will give optimum perfor­mance if the three output phases are loaded within 20 percent of each other.
3. Plan the routing to ensure that the unit can move through all aisle ways, doorways, and around corners without risking damage. If the modules and batteries must be moved by elevator, check the size of the door openings and the weight-carrying capacity of the elevator.
2 Installation Manual
3. UNLOADING AND HANDLING
4. INSPECTIONS
Because the weight distribution in each UPS and ancillary cabinet is uneven, use extreme care during handling and transport. Your installation may also include Battery Cabinets, a Bypass Transformer Cabinet and a Maintenance Bypass Cabinet, Panelboard or Switchboard.
WARNING
EXERCISE EXTREME CARE WHEN HANDLING UPS CABINETS TO AVOID EQUIPMENT DAMAGE OR INJURY TO PERSONNEL. THE UPS MODU LE CAN WEIGH UP TO TWO TONS. THE BATTERY CABINETS WEIGH UP TO 5100 POUNDS.
THE UPS MODULES ARE HEAVIER IN THE BACK THAN THE FRONT BECAUSE OF THE WEIGHT OF THE MAGNETICS. LOCATE CENTER OF GRAVITY SYMBOLS BEFORE HANDLING CABINET. TEST LIFT AND BALANCE THE CABINET BEFORE TRANSPORTING. MAINTAIN MINIMUM TILT FROM VERTICAL AT ALL TIMES.
4.1. External Inspections
1. While the UPS system is still o n the truck, inspect the equi p men t and shi ppin g container(s) for any signs of damage or mishandling.

5. EQUIPMENT LOCAT ION
1. Handle cabinet(s) in accordance with WARN­INGS in Section 3. Use a suitable material
handling device to move each cabinet to its final location. Exercise extreme care
because of the uneven weight distribu­tion. Carefully lower the cabinets to the floor
and position them for reconnection, if applica­ble.
2. Verify that the UPS system is installed in a clean, cool and dry location. Observe the location of overhead water lines for fire sprinkler systems. Avoid placing the UPS and related equipment directly under water lines or within range of a sprinkler head.
3. Installation and serviceability will be easier if adequate access is provided on all sides of the equipment, but only front access is required.
a. Verify that there is adequate clearance to
open cabinet doors (4 feet is recommended ). See drawings and local codes.
b. V erify that there is adequate area in fron t of
circuit breakers to perform maintenance. Check installation drawings for location of breakers. Check with local codes.
c. Verify that there is adequate clearance
above all cabinets to allow exhaust air to flow without restriction (2 feet minimum, unobstructed).
4. Connec t the cabinets, internal cables and bus bars, if applicable.
6. BATTERY INSTALLATION
6.1. Battery Safety Precautions
Battery installation and servicing should be performed or supervised by personne l knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.
Be sure to observe the grounding recommendations in Section 7 when installing batteries. When replacing batteries, use the same number and type of batteries.
CAUTION
Lead-acid batteries contain hazardous materials. Batteries must be ha ndled, transported, and recycled or discarded in accordance with federal, state, and local regulations. Because lead is a toxic substance, lead-acid batteries should be recycled rather than discarded.
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. Do not dispose of battery or batteries in a fire. The battery may explode.
A battery can present a risk of electrical shock and high short-circuit current. The following precautions should be observed when working on batteries:
1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
3. Wear rubber gloves and boots.
4. Do not lay tools or metal parts on top of batteries.
5. Disconnect charging source prior to connecting or disconnecting battery terminals.
6. Determine if the battery is inadver­tently grounded. If it is inadvertently grounded, remove source of ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock will be reduced if such grounds are removed during installation and maintenance.
Lead-acid batteries can present a risk of fire because they generate hydrogen gas. The following procedures should be followed:
1. DO NOT SMOKE when near batterie s.
2. DO NOT cause flame or spark in
battery area.
3. Discharge static electricity from body
before touching batteries by first touching a grounded metal surface.

métalliques sur le dessus des accumulateurs.
5. Interrompre la source de charge avant de raccorder ou de débrancher les bornes de la batterie d'accumulateurs.
6. Déterminer si l'accumulateur est mis à la terre par erreur. Si oui, défaire cette mise à la terre. Tout contact avec un accumulateur mis à la terre peut se traduire en un ch oc élec trique. La possibilitié de tels chocs sera réduite si de telles mises à la terre sont débranchées pour la durée de l'installation ou de l'entretien.
Les accumulateurs plomb-acide présentent un risque d'incendie parce qu'ils génèrent des gaz à l'hydrogène. Les procédures suivantes devront être respectées.
1. NE PAS FUMER lorsque près des accumulateurs.
2. NE PAS produire de flammes ou d'étincelles près des accumulateurs.
3. Décharger toute électricité statique présente sur votre corps avant de toucher un accumulateur en touchant d'abord une surface métallique mise à la terre.
DANGER
L'électrolyte est un acide sulfurique dilué qui est dangereux au contact de la peau et des yeux. Ce produit est corrosif et aussi conducteur electrique. Les procédures suivantes devront être observées:
1. Porter toujours des vêtements protecteurs ainsi que des lunettes de protection pour les yeux.
2. Si l'électrolyte entre en contact avec l a peau, nettoyer immédiatement en rinçant avec de l'eau.
3. Si l'électrolyte entre en contact avec les yeux, arroser immédiatement et généreusement avec de l'eau. Demander pour de l'aide médicale.
4. Lorsque l'électrolyte est renversée, la surface affectée devrait être nettoyée en utilisant un agent neutralisant adéquat. Une prati que cou­rante est d'utiliser un mélange d'appro xima­tivement une livre (500 grammes) de bicarbonate de soude dans approximativement un gallon (4 litres) d'eau. Le mélange de bicar­bonate de soude devra être ajouté jusqu'à ce qu'il n'y ait plus apparence de réaction (mousse). Le liquide résiduel devra être net­toyé à l'eau et la surface concernée devra être asséchée.
Liebert Series 600T UPS, 65-225 kVA, Single Module 5
6.2 Battery Cabinets
Optional battery cabinets are available from Liebert and other qualified vendors. Consult your submittal package for details.
The same model battery cabinet may be paralleled in multiple cabinet strings for additional capacity. Battery capacity (in minutes) a t your installation will depend on cabinet model, number of cabinets, and amount of critical load on the UPS.
1. Handling. The Battery Cabinet weighs up to 5100 pounds. Fork lift slots are provided in the base of 100-225 kVA cabinets for easy handling. Fork lift forks or a pallet jack can be used between the casters of the 65 and 80 kVA battery cabinets.
2. Cabinet Inspection. Remove all panels and visually inspect the batteries, bus connections, and cabinet for any damage. If any foam blocks were placed between shelves to restrain movement during shipment, remove them now.
Exercise caution; voltage is present within the Battery Cabinet even before installation. If there are signs of damage, do not proceed. Call Liebert Global Services at 1­800-542-2378.
3. Battery Storage. The batteries used in the
Battery Cabinet retain their charge well. The batteries can be stored for up to six months without any appreciable deterioration. Self­discharge rate of the ba tteries is app roximately 3% per month when the batteries are stored in temperatures of 15°C to 25°C (59°F to 77°F). If the Battery Cabinet must be stored for longer than six months, contact Liebert Global Services.
4. Installation. The Battery Cabinet(s) can be located conveniently to the left side of the 65­225 kVA UPS module. The front-access-only­design eliminates side and rear service clearance requirements.
7. Service Clearance. Allow fron t acc es s to the Battery Cabinet at all times for maintenance and servicing. Electrical codes require that the Battery Cabinet be installed with no less than 3 feet (1 meter) of clearance at the front of the cabinet when operating. Side and rear pan els do not require service clearance.
8. Side Panels. Remove protective side panels to connect battery cabinets together. Do not remove the shield plate, explained below.
9. Shield Plate. The shield plate in 125 kVA Battery Cabinets should be on the side toward the UPS system. Mov e the shie ld if req uir ed by your Battery Cabinet location.
10. Cables. Cables may be run between battery cabinets through cutouts in the top of the cabinets, eliminating the need for external conduit runs. Route cables before moving
cabinets into fi nal position for bolting together. Remove top panels for access. Refer
to Figures 16 and 17 or your submittal drawings for instructions on wiring cabinets in parallel.
11. Grounding. The battery cabinets have ground studs near the bus bar connections. Use an equipment grounding conductor to connect the lugs of the cabinets to gether and to connect the cabinets to the ground bus bar in the UPS module.
CAUTION
Cables between batteries and modules should be run in matched pairs, positive­with-negative. Grouping like-polarity cables together (i.e. positive-with-positive and negative-with-negative) can cause stress or damage to the cables, conduit or buswork.
5. Re-Installation. If it later becomes necessary
to move the Battery Cabinet to another location, contact Lieb ert Global Services to inspect the internal battery hold-down straps.
6. Environment. Locate the Battery Cabinet in a clean, dry environment. Recommended temperature range for optimum performance and lifetime is 20-25°C (68-77°F).
6 Installation Manual
6.3 Open-Rack Batteries
When batteries other than Liebert Battery Cabinets are used, a remote battery disconnect switch with overcurrent protection is required per the National Electrical Code. Refer to Figures 53 and 54. Contact your Liebert sales representative.
1. Install battery racks/cabinets and batteries per manufacturer's installation and maintenance instructions.
2. Verify battery area has adequate ventilation and battery operating temperature complies with manufacturer's specification.
3. Ensure that battery racks are properly grounded according to code requirements in your area.
If you have any questions concer ning batteries, battery racks, or accessories, contact Liebert Global Services at 1-800-543-2378.
CAUTION
Cables between batteries and modules should be ru n in matche d pairs, positive­with-negative. Grouping like-polarity cables together (i.e. positive-with-positive and negative-with-negative) can cause stress or damage to the cables, conduit or buswork.
7. CONFIGURING YOUR NEUTRAL AND GROUND CONNECTIONS
Improper grounding is the largest single cause of UPS installation and start-up problems. This is not an easy subject, since grounding techniques vary significantly from site to site, depending on several factors. The questions you should ask are:
What is the configuration of the input power
source? Most of the recommended schemes f or UPS grounding require grounded-wye ser­vice. The UPS system requires a bypass neu­tral for sensing and monitoring the quality of the bypass input. If the building service is ungrounded delta or corner-grounded delta, contact your Liebe rt re pres ent ati ve to ens ure your system includes the Artificial Neutral or Isolated Neutral kit.
Does the system have a bypass isolation
transformer? Systems with 480 VAC (or 600 VAC) input and 208 VAC output require a bypass isolation transformer. In some cases, it may be necessary to treat that transformer as a “separat ely derived source” with its own grounding electrode. See page 10 for details.
What are the UPS input and output voltages?
Systems with 480 VAC input and output have significantly different needs than systems with 480/208 VAC or 208/208 VAC.
What is the connected load? Does the critical
load consist of one or more Power Distribu­tion Units (PDUs)? Do the PDUs have isola­tion transformers?
The following sections discuss recommended grounding procedures for various system configurations.
Liebert Series 600T UPS, 65-225 kVA, Single Module 7
NOTE
Some UPS modules are equipped with input isolation transformers. However, these transformers have no effect upon any system grounding considerations. These modules will be grounded exactly as shown in the following examples.
GROUNDING ELECTRODE PER NEC 250-24
Figure 1. Preferred Grounding Configuration, 480 or 600 VAC input and output
7.1. Preferred Grounding Configuration, 480 or 600 VAC Input and Output, Isolated Power Distribution Units, Wye-Connected Service
One of the most-common configurations of the Series 600T UPS is the Single Module System with 480 VAC input, 480 VAC output, and a connected load consisting of multiple Power Distribution Units (PDUs) with isolation transformers in the PDUs to produce 208 VAC. For Canadian customers, the UPS modules usually have 600 V AC input and output. The same principles apply if the connected load is an isolation transformer feeding various loads. Figure 1 above shows a typical installation.
Notice that the UPS module main input and bypass input are connected to a grounded-wye service. In this configuration, the UPS module is not considered a separately derived source. The UPS module output neutral is solidly connected to the building service neutral, which is bonde d to the grounding conductor at the service entrance equipment
The isolation transformers in the PDUs are considered a separately derived source. Therefore the PDU neutral should be bonded to the PDU grounding conductor and connected to a local grounding electrode in compliance with NEC 250-
26. Advantages of this configuration include:
A measure of common-mode noise attenua­tion, since the isolation (common-mode rejec­tion) occurs as close to the load as practical (i.e. at the PDU).
The UPS module can be located remotely from the PDU without compromising com­mon-mode noise performance.
By using UPS modules with 480 VAC input and output and creating 208 V AC at the PDU, smaller and less costly power feeders can be used and less voltage drop (as a percent of nominal) occurs.
NOTE
Impedance-grounded wye sources must be grounded in accordance with Section 7.5.
8 Installation Manual
Figure 2. Alternative Grounding Configuration, 480 or 600 VAC input and output
7.2 Alternative Grounding Configuration, 480 or 600 VAC Input and Output, Isolated Power Distribution Units, Wye-Connected Service
This configuration is similar to that shown in Section 7.1, except that the service entrance neutral is not brought into the UPS module. In this configuration, the UPS output transformer is considered a separately derived source. The UPS module neutral is bonded to the UPS ground, which is connected to a local groundi ng electrode in accordance with NEC 250-26.
Please note that this configuration represents a price/performance trade-off. Whenever the UPS module transfers to or from bypass, two AC sources (input and bypass) are briefly connected together and circulating current must flow. In the previous configuration, the current flows through the neutral conductor. In this configuration, the current flows through the ground path, possibly tripping ground fault interruptors (GFIs) and distorting the bypass waveform reference. Proper adjustment of ground fault interrupters is necessary to avoid unwanted tripping.
This configuration is reserved for those applications which meet all the following criteria:
The facility has Wye-connected service
The module rectifier input and bypass input are fed from the same source
The connected load is strictly 3-wire (such as one or more PDUs ) an d doe s no t require a neutral from the UPS
Special precautions are taken to prevent trip­ping the ground fault interruptors. The time delay should be set to at least 30 cycles to pre­vent tripping when the UPS performs a transfer or retransfer operation.
CAUTION
Failure to properly set the ground fault interruptors could cause loss of power to the critical load.

Figure 3. Preferred Grounding Configuration, 480 or 600 VAC input and 208 VAC output
7.3. Preferred Grounding Configuration, 480 or 600 VAC Input, 208VAC Output, and Isolated Bypass
Another configuration in this power range is the Single Module System with 480 or 600 VAC input, 208 VAC output, a Bypass Isolation Transformer and a connected load consisting of multiple distribution panelboards or switchboards. Figure 3 above shows a typical installatio n.
The Bypass Transformer provides isolation and steps down the voltage to the bypass inputs. The Bypass T ra ns former and t he UPS modul e toget her constitute a separately derived system, since there is no direct electrical connection bet ween the input (service entrance) circuit conductors and the output circuit conductors.
NOTE
The illustration above shows a wye­connected source, but the same grounding scheme would apply for a delta source at the service entrance.
The bonding of the neutral to the grounding conductor can theoretically be done at either the UPS module or the Bypass Transformer. However, we recommend bonding at the Bypass Transformer because the UPS module will sometimes be powered down for maintenance and its output transformer will be out of the circuit. The neutral should be bonded to ground and a local grounding electrode should be installed at the Bypass Transformer, per NEC 250-30.
Features of this configuration include:
The UPS receives its bypas s neutral from the Bypass Transformer
The output is isolated from the input circuit conductors, and
Some amount of common-mode noise attenu­ation can be obtained for sensitive loads if the UPS module and Bypass Transformer are located close to sensitive loads.

GROUNDING ELECTRODE PER NEC 250-24
Figure 4. Preferred Grounding Configuration, 208 VAC input and output
7.4. Preferred Grounding Configuration, 208 VAC Input and Output, Non­Isolated Load, Wye-Connected Service
A few applications in this power range have 208 VAC input and output, and a connected load consisting of multiple Power Distribution Units (PDUs), panelboards, switchboards or other items of load equipment which do not have isolation transformers.
Notice in Figure 4 above that the UPS module main input and bypass input are connected to a grounded-wye service. In this configura tion, the UPS module is not considered a separately d erived source.
The UPS module output neutra l and the load neutral are solidly connected to the building service neutral, which is bonded to th e grounding conductor at the service entrance equipment.
This arrangement is typical for systems with 208 VAC input and output. However, it does not provide any isolation or common-mode noise attenuation for sensitiv e loa d s.

7.5. Grounding Configuration, 480 or 600 VAC Input and Output, Delta Source or Impedance-Grounded Wye
As previously mentioned, Series 600T UPS modules require a bypass input neutral for sensing and monitoring. With a wye-connected input source, the installer should always connect the building service neutral to the module output neutral to achieve this. When the building service is delta-connected, however, the installer must take special steps to ensure reliable UPS functioning.
If building service is ungrounded delta (and there is no intent to operate with one corner of the delta grounded, either on purpose or accidentally), the UPS requires the Series 600T Artificial Neutral Kit for proper operation. This kit uses a resistor network to create a reference point for the bypass input. In this case, the UPS output neutral must be bonded to the UPS ground. See Figure 5 above.
If the building service is corner-grounded delta or an impedance-grounded wye, the UPS requires the Series 600T Isolated Neutral Kit. This kit uses control isolation transformers to create a reference point. For this application, the UPS output neutral must not be bonded to the UPS ground.

7.6. Preferred Grounding Configuration, 480 or 600 VAC Input and Output, with Power-Tie™ Switchgear
Single Module Systems c an be used wit h Power-T ie switchgear to provide dual critical load busses. The Power-Tie switchgear permits transferring critical loads from one critical bus to the other so that one UPS module and associated breakers can be de­energized for maintenance. Certain configurations of Power-T ie equipment also permit th e operator to continuously parallel the output of the UPS modules.
In tied systems, each UPS module must have its neutral solidly connected to its own building service neutral and to the Power-Tie switchgear neutral. See Figure 6 above.
NOTE
It is essential to run a neutral connection between the tie switchgear and both UPS modules as shown in the illustration above.

TO OUTPUT DISTRIBUTION
7.7. Preferred Grounding Configuration, Battery Systems
Large, open-rack battery systems are normally either locally grounded or left ungrounded, depending on local code requirements.
Battery cabinet systems, on the other hand, should be grounded to the UPS ground bus bar. Figure 7 above illustrates how a simple one-cabinet system would be grounded. For systems with multiple cabinets, the same configuration would apply. However , for simplicity the installer can connect all the battery cabinet grounds together and run a single ground conductor (in the same conduit as the phase conductors) to the UPS ground.

8. WIRING CONSIDERATIONS
8.1. Power Wiring
Refer to Site Planning Data (Appendix A) and the installation drawings. Determine AC currents for your system based on kVA, kW, voltage, and options. Also refer to equipment nameplate for the model number, rating, and voltage. For wire termination data, refer to Tables 1-3.
1. Power wiring -- rectifier input, bypass input, UPS output, and battery cables -- must be run in individual, separate conduit or cable tray. Refer to the Outline and Terminal Details drawings (Figures 11-13 and 35-39) for location of the various power connections within the UPS.
CAUTION
Power and control wiring must be separated!
2. Observe local, state and national electrical
codes. Verify utility power and its overcurrent protection rating will accommodate the UPS input rating, including battery recharging.
3. A safety ground wire must be run from building ground to ground point in the UPS Module Cabinet, the Battery Cabinet and the Power-Tie™ switchgear cabinet. See Sections
7.1 through 7.7. The g rounding conducto r shall comply with the following conditions of installation:
a. The insulated grounding conducto r must be
sized in accordance with the NEC and local codes. It must be green (with or without yellow stripes) and be installed as part of the branch circuit that supplies the unit or system.
connected to earth ground at the service equipment.
4. Observe clockwise phase rotation of all power wiring. Phase A leads Phase B leads Phase C. A qualified electrician should check the phase rotation.
5. Power cables must be rated for less than 2 volts line drop at maximum rated system current.
6. Use 75°C copper wire. Select wire size based on the ampacities in Table 310-16 and associated notes of the National Electrical Code (NFPA
70) reprinted on page 24 of this manual.
CAUTION
The weight of power cables must be adequately supported to avoid stress on bus bars and lugs. The following restraining method is recommended to both to support cable weight and control cable movement during external fault conditions: Wrap line cables together at 6 inches and 12 inches from the terminals with 5 wraps of 3/8 inch nylon rope or equivalent (tensile strength of 2000 pounds). Support remainder of cable w ith 5 wraps every 6 inches or 1 wrap every 1 inch.
7. If site equipment includes a backup generator
and automatic transfer switch(es), consult the manufacturers of those devices for information on sizing and interfacing to the UPS system.
8. The installing contractor can remove the access plates from the top left or top right sides of the UPS in order to cut entry hole s for conduit . For units with bottom-entry cable access, there is a separate (third) access plate in the base of the unit, under the cable access wireway.
b. The grounding conductor described abo ve is
to be grounded to earth at th e se rvic e equi p­ment or, if supplied by a separately derived system, at the supply transformer or motor­generator set in accordance with the instructions in Section 7 of this Manual.
c. The attachment-plug receptacles in the
vicinity of the unit or system are al l to be of a grounding type, and the grounding con­ductors serving these receptacles are to be

8.2. Control Wiring
8.3. Battery Wiring
Control wiring must be stranded and tinned and run in individual separate steel conduit. Control wiring must be separated from power wiring. In addition, each control wiring cable group should be run in a separate conduit to minimize control signal interference.
If your system has any in stalled options, special wire lists will be included in your Submittal Drawing Package. Contact your Liebert Sales Representative for assistance if the Submittal drawings have been lost or misplaced.
All control cable groups are connected to different Interface Modules (IFMs) inside the UPS. Figure 29 shows the typical location of each IFM inside the UPS. The position of a particular IFM may be different for your UPS, depending upon the model and the installed options.
NOTE
The UPS control and communication wiring are considered Class 2 circuits by NEC standards. However, NEC Class 1 wiring methods are required for these circuits to ensure proper operation of the UPS.
Power wiring to the Battery Cabinet connects positive, negative, and ground power cables from the Battery Cabinet to the associated UP S. Connection of the UPS to the Battery Cabinet serves to both charge and discharge the batteries (when needed). The battery disconnect (circuit breaker) requires a control cable. Liebert Battery Cabinets include power and control cables to join multiple cabinets together into a system. Additional (field-supplied) power or control wiring might be necessary to connect the battery cabinet system to the UPS. Refer to Figures 16-17.
DANGER
A BATTERY INTERCELL CONNECTION ON EACH TIER IS DISCONNECTED FOR SAFETY DURING SHIPMENT. DO NOT COMPLETE THESE CONNECTIONS. THE LIEBERT GLOBAL SERVICES REPRESEN­TATIVE WILL COMPLETE THESE CON­NECTIONS AS PART OF START-UP. A N IM­PROPERLY INSTALLED UNIT CAN RESULT IN INJURY TO PERSONNEL OR DAMAGE TO EQUIPMENT.
CAUTION
Be sure polarity is correct when wiring the Battery Ca binet to the connected equipment (positive to positive; negative to negative). If polarity is not correct, fuse failures or equipment damage can result.
CAUTION
DC power cables should be installed in conduit with conductors in matched pairs (positive and negative).
NOTE
Inspection of the battery installation is a service that can be provided by Liebert. A Battery Specialist can perform a detailed inspection of the entire battery system to ensure it meets current IEEE standards. This inspection service is recommended because batteries are a critical part of the UPS system.
