IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation of your
Series 610 UPS and batteries.
WARNING
!
Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to
personnel. The UPS module weight ranges from 16,700 to 17,550 lbs. (7575 to 7961kg),
including input transformer. The battery cabinets weigh from 3060 to 5300 lbs. (1388 to
2404kg).
Locate center of gravity symbols and determine unit weight before handling each
cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from
vertical at all times.
Slots at the base of the modules and battery cabinets are intended for forklift use. Base slots
will support the unit only if the forks are completely beneath the unit.
Follow all battery safety precautions when installing, charging or servicing batteries. In
addition to the hazard of electric shock, gas produced by batteries can be explosive and
sulfuric acid can cause severe burns.
In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or
those approved for use in fighting electrical fires.
Extreme caution is required when performing maintenance.
Be constantly aware that the UPS system contains high DC as well as AC voltages.
Check for voltage with both AC and DC voltmeters prior to making contact.
Read this manual thoroughly, paying special attention to the sections that apply to your installation,
before working with the UPS. Retain this manual for use by installing personnel.
WARNING
!
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 of puddles of water, excess
moisture and debris.
Special safety precautions are required for procedures involving handling, installation and
maintenance of the UPS system and the battery. Observe all safety precautions in this
manual before handling or installing the UPS system. Observe all precautions in the
Operation and Maintenance Manual, before as well as during performance of all maintenance
procedures. Observe all battery safety precautions before working on or near the battery.
This equipment contains several circuits that are energized with high voltage. Only
test equipment designed 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 potential electric
charges may exist at the capacitor banks and at the batteries.
All power and control wiring should be installed by a qualified electrician. All power
and control wiring must comply with the NEC and applicable local codes.
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 insulating shoes for isolation from direct contact with the floor (earth ground).
One person should never work alone, even if all power is removed from the equipment. A
second person should be standing by to assist and summon help in case an accident should
occur.

1.0 INSTALLATION CONSIDERATIONS
Install your Series 610 UPS in accordance with the submittal drawing package and the following procedures.
A Liebert authorized representative must perform the initial system check-out and start-up to ensure
proper system operation. 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-LIEBERT 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 9
through 22 and 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 and the weight of any moving equipment. The
UPS modules can weigh from 16,700 to 17,550 lbs. (7575 to 7961kg). The battery cabinets weigh
from 3060 to 5300 lbs. (1388 to 2404kg) each. Refer to Appendix A.
WARNING
!
Locate center of gravity symbols and determine unit weight before handling cabinet.
3. Plan the route to ensure that the unit can move through all aisleways and 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.
4. Refer to information later in this manual regarding the optional battery cabinet(s), Maintenance
Bypass Cabinet and Transformer Cabinet. 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 77°F (25°C). Relative humidity must be less
than 95%, non-condensing. Note that room ventilation is necessary, but air conditioning may not
be required. Maximum ambient operating temperature is 104°F (40°C) without derating. The
batteries should not exceed 77°F (25°C). At elevations above 4000 ft. (1219m), temperature
derating may be required for full power output—consult your Liebert sales representative or call
1-800-LIEBERT.
7. Even though your Liebert UPS unit is 92 to 94% efficient, the heat output is substantial. For more
specific information, see 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 output 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.
9. During normal UPS operations, short-term overload current demand from the bypass source may
reach 10x the UPS output current rating. This overload current demand may be caused by the
magnetizing inrush current of one or more downstream transformers or faults on downstream
branch circuits. The instantaneous trip point(s) of the upstream bypass feeder breaker(s) must be
set to support these temporary overloads. The magnitude of short-term overload bypass current
demand is typically six to eight times the UPS current rating, but must be determined by analysis
on a per-site basis. This analysis, generally known as an End-to-End Fault Coordination Study,
must be done by a Registered Professional Engineer experienced in this activity and familiar with
local codes and related requirements.
NOTE
While Liebert can provide typical guidelines, the responsibility for the proper breaker trip
settings outside of the Liebert-manufactured UPS equipment resides with the owner. Contact
Liebert Global Services at 1-800-LIEBERT for further details.
Installation Considerations
3
Installation Considerations
10. A breaker coordination study should be performed to ensure proper handling of fault currents.
NOTE
The instantaneous trip setting of the breaker feeding the UPS bypass input should be high
enough to accommodate short-duration overloads. The bypass static switch inside the UPS can
draw up to 10 times the system’s rated current for up to three cycles.
4
2.0 UNLOADING AND HANDLING
UPS modules are shipped in split cabinets to allow ease of handling. Because the weight distribution
in the cabinets is uneven, use extreme care during handling and transport. Your installation may also
include battery cabinets and a System Control Cabinet.
WARNING
!
Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to
personnel. The UPS module weight ranges from 16,700 to 17,550 lbs. (7575 to 7961kg).
Battery cabinets weigh from 3060 to 5300 lbs. (1388 to 2404kg).
Locate center of gravity symbols before handling cabinet. Test lift and balance the cabinet
before transporting. Maintain minimum tilt from vertical at all times.
Slots at the base of the unit and battery cabinets are intended for forklift use. Base slots will
support the unit only if the forks are completely beneath the unit.
To reduce the possibility of shipping damage, cabinets are shored with 2x4 bracing, secured with
screw-type nails. This shoring must be carefully removed prior to unloading.
CAUTION
!
Extreme care is necessary when removing shoring braces. Do not strike cabinet with
hammers or other tools.
Unloading and Handling

3.0 INSPECTIONS
3.1 External Inspections
1. While the UPS system is still on the truck, inspect the equipment and shipping container(s) for
any signs of damage or mishandling. Do not attempt to install the system if damage is apparent.
If any damage is noted, file a damage claim with the shipping agency within 24 hours and contact
Liebert Global Services at 1-800-LIEBERT to inform them of the damage claim and the condition
of the equipment.
2. Locate the bag containing the keys for the front access door. The bag is attached to the cabinet.
3. Compare the contents of the shipment with the bill of lading. Report any missing items to the
carrier and to Liebert Global Services immediately.
4. Check the nameplate on the cabinet to verify that the model number corresponds with the one
specified. Record the model number and serial number in the front of this installation manual. A
record of this information is necessary should servicing become required.
3.2 Internal Inspections
1. Verify that all items have been received.
2. If spare parts were ordered, verify arrival.
3. Open doors and remove cabinet panels to check for shipping damage to internal components.
4. Check for loose connections or unsecured components in the cabinet(s).
5. Check for installation of circuit breaker line safety shields. There should be no exposed circuit
breaker terminals when the cabinet doors are opened.
6. Check for any unsafe condition that may be a potential safety hazard.
7. UPS modules are shipped with internally mounted shipping brackets. The shipping brackets
(painted orange) must be removed from the rear (remove rear panels). The installer must remove
the orange shipping brackets before final equipment placement, particularly if rear access will be
restricted.
Inspections
CAUTION
!
Failure to remove orange shipping brackets from transformers may cause restricted airflow
within the UPS. This could cause overheating or reduction of UPS capacity. In some cases, it
could cause damage to the UPS module, and such damage would not be covered under the
factory warranty. If you foresee a situation where the UPS will be relocated in the near
future, the brackets should be removed and stored elsewhere until they are needed.

4.0 EQUIPMENT LOCATION
1. Handle cabinet(s) in accordance with the safety precautions in this manual, especially in these
sections:
• Battery Cabinet Precautions—inside front cover
• Important Safety Instructions—page 1
• 2.0 - Unloading and Handling—page 5
• 5.0 - Battery Installation—page 8
Use a suitable material handling device to move cabinet to its final location. Exercise extreme
care because of the uneven weight distribution. Carefully lower the cabinet to the floor.
2. Verify that the UPS system is installed in a clean, cool and dry location.
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 ft. (1.2m) is recommended.
NEC requires sufficient clearance in front of the equipment to fully open all doors without
restriction. See drawings and local codes.
b. Verify that there is adequate area in front 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. The minimum clearance is 2 ft. (0.6m), unobstructed by conduit or any other
items. Liebert recommends against using top-feed air conditioning systems.
4. Align the UPS cabinet, battery cabinets (if used) and optional transformer and maintenance
bypass cabinets, as shown in the Outline Drawing (Figure 9) and your submittal package.
5. Connect the cabinets, internal cables and busbars, if applicable. Internal control connections
should be left disconnected for later installation by Liebert LGS Customer Engineers.

5.0 BATTERY INSTALLATION
5.1 Battery Safety Precautions
Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized personnel away from batteries.
Be sure to observe the grounding recommendations in 6.0 - Configuring Your Neutral and
Ground Connections when installing batteries. When replacing batteries, use the same number
and type of batteries.
CAUTION
!
Lead-acid batteries contain hazardous materials. Batteries must be handled, transported and
recycled or discarded in accordance with federal, state and local regulations. Because lead is a
toxic substance, lead-acid batteries must be recycled rather than discarded.
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin
and eyes. It is toxic. Do not dispose of battery or batteries in a fire. The battery may explode.
Do not install any batteries that are cracked, leaking or show other signs of damage. Contact
Liebert Global Services or your local Liebert representative.
A battery can present a risk of electrical shock and high short circuit current. The following
precautions should be observed when working on batteries:
Battery Installation
• Remove watches, rings and other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if battery is inadvertently grounded. If 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:
• DO NOT SMOKE when near batteries.
• DO NOT cause flame or spark in battery area.
• Discharge static electricity from body before touching batteries by first touching a grounded
metal surface.
• After replacing battery jars in a battery cabinet, replace the retaining straps that hold the
jars in place on the shelves. This will limit accidental movement of the jars and connectors
should the cabinet ever need to be repositioned or relocated. Regular maintenance of the
battery module is an absolute necessity. Periodic inspections of battery and terminal voltages, specific gravity and connection resistance should be made. Strictly follow the procedures outlined in the battery manufacturer’s manual, available on the manufacturer’s Web
site.

• Éliminer l'électricité statique du corps avant de manipuler les batteries en touchant d'abord
une surface métallique mise à la terre.
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 :
• Porter toujours des vêtements protecteurs ainsi que des lunettes de protection pour les yeux.
• Si l’électrolyte entre en contact avec la peau, nettoyer immédiatement en rincant avec de l’eau.
• Si l’électrolyte entre en contact avec les yeux, arroser immédiatement et généreusement
avec de l’eau. Demander pour de l’aide médicale.
• Lorsque l’électrolyte est renversée, la surface affectée devrait être nettoyée en utilisant un
agent neutralisant adéquat. Une pratique courante est d’utiliser un mélange d’approximativement 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.

5.3 Battery Cabinets
Optional battery cabinets are available from Liebert and other qualified vendors. Consult your submittal package for details.
Several models of optional battery cabinets with varying run times are available. Each model is 78"
(1981mm) high and has forklift slots. Refer to the Battery Cabinet submittal drawings if a battery
cabinet is to be used. The battery cabinet cells range from 90 to 150 ampere-hours. The same model
battery cabinet may be paralleled in multiple cabinet strings for additional capacity. Battery capacity
(in minutes) at your installation will depend on cabinet model, number of cabinets, and amount of
critical load on the UPS.
1. Handling. The battery cabinet weighs from 3060 to 5300 lbs. (1388 to 2404kg). Forklift slots are
provided for ease of handling.
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 1-800-LIEBERT.
3. Battery Storage. The batteries used in the battery cabinet retain their charge well. The
batteries can be stored indoors in a temperature-controlled environment, for up to six months
without any appreciable deterioration. Self-discharge rate of the batteries is approximately 3%
per month when the batteries are stored in temperatures of 59°F to 77°F (15-25°C). If the battery
cabinet must be stored for longer than six months, contact Liebert Global Services. The battery
cabinet should never be stored outdoors or on a loading dock.
4. Installation. The battery cabinet(s) can be located conveniently next to the UPS module. The
front-access-only-design eliminates side and rear service clearance requirements.
5. Reinstallation. If at any time it becomes necessary to move the battery cabinet to another
location, contact Liebert 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 68°F to 77°F (20-25°C).
7. Service Clearance. Allow front access 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 ft. (1m)
of clearance at the front of the cabinet when operating. Side and rear panels do not require service
clearance.
8. Side Panels. To connect battery cabinets together, remove the protective side panels by
removing the retaining screws that hold the side panels in place.
9. Cables. Multiple battery cabinets may be bolted together in a daisy-chain configuration. Cables
for this setup may be run between paralleled battery cabinets through cutouts in the top of the
cabinets, eliminating the need for external conduit runs. Route cables before moving
cabinets into final position for bolting together. Low voltage control wiring must be kept
separate from the power wiring. Remove top panels for access. No top or bottom entry cables are
required, except for remotely located cabinets, which require conduits. Refer to your submittal
drawings for instructions on wiring cabinets in parallel.
Battery Installation
NOTE
The 1000kVA UPS module is approximately 2 to 6 in. (51-152mm) deeper than the battery
cabinet and is not designed to bolt directly to it.
10.
Grounding. The battery cabinets have ground studs near the busbar connections. Use an
equipment grounding conductor to connect the lugs of the cabinets together and to connect the
cabinets to the ground busbar in the UPS module.

5.4 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 Required Battery Disconnect Rating in the site planning data tables in Appendix A for recommended overcurrent protection
ratings. Contact your Liebert sales representative for more information.
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. Installations using vented lead-acid batteries MUST have adequate
ventilation to remove explosive gases per local and national codes.
3. Low voltage control wiring must be kept separate from power wiring and run in separate
conduits.
4. Ensure that battery racks are properly grounded according to code requirements in your area.
If you have any questions concerning batteries, battery racks or accessories, contact your local sales
representative or Liebert Global Services at 1-800-LIEBERT.
CAUTION
!
Cables between batteries and the UPS should be run in matched pairs,
positive-with-negative, within each conduit or cable run. 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.

Configuring Your Neutral and Ground Connections
6.0 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 for 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 Liebert representative for details about Isolated Neutral kits.
A Power-Tie or distributed redundant system has different grounding requirements from standalone UPS modules. If using one of those systems, refer to Liebert’s Power-Tie configuration user
manual, SL-30030.
• 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 “separately derived source” with its own grounding electrode.
• What are the UPS input and output voltages? Systems with 480 VAC input and output have significantly different needs from 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?
Proper grounding should be based on NEC Section 250, but safe and proper equipment operation
requires further enhancements. The following pages detail Liebert’s recommendations for grounding
various system configurations to ensure optimal UPS system performance.
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 Figures 1 through 7.
CAUTION
!
The UPS ground lug must be solidly connected to the service entrance ground by an
appropriately sized wire conductor per NEC Article 250. Each conduit or raceway containing
phase conductors must also contain a ground wire, both for UPS input and output, which are
solidly connected to the ground terminal at each termination point. Conduit-based grounding
systems tend to degrade over time. Therefore, using conduit as a grounding conductor for UPS
applications may degrade UPS performance and cause improper UPS operation.
