Liebert® Large UPS Battery System. Read this manual thoroughly, paying special attention to the sections that apply to
your installation, before working with the UPS and battery system. Retain this manual for use by installing personnel.
WARNING! Risk of electrical shock. Can cause personal injury or death. This UPS has several circuits that are
energized with high DC as well as AC voltages. Check for voltage with both AC and DC voltmeters before
working within the UPS. Check for voltage with both AC and DC voltmeters before making contact. Only
properly-trained and qualified personnel wearing appropriate safety headgear, gloves, shoes and glasses
should be involved in installing the equipment or preparing for installation. When performing maintenance
on any part of the equipment under power, service personnel and test equipment should be standing on
rubber mats. In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or
those approved for use in fighting electrical fires.
WARNING! Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or death.
Because the weight distribution in the cabinet is uneven, use extreme care while handling and transporting.
Take extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel. 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. For weights, see Specifications
on page 29.
WARNING! Risk of electrical shock and fire. Can cause equipment damage, personal injury or death. Only
normal safety precautions are necessary under typical operation and with all UPS doors closed. The area
around the UPS system should be kept free of puddles of water, excess moisture and debris. Only test
equipment that is 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 with the UPS or using
tools to work on any UPS component. Dangerously high potential electric charges may exist at the capacitor
banks and at the DC connections even when input power is turned Off. All wiring must be installed by a
properly trained and qualified electrician. All power and control wiring must comply with all applicable
national, state and local codes. One person should never work alone, even if all power is disconnected from
the equipment. A second person should be standing-by to assist and to summon help in case of an accident.

2 MECHANICAL INSTALLATION
2.1 Pre-Installation Planning
This section describes the requirements that must be taken into account when planning the positioning and cabling of the
UPS and related equipment.
Installing personnel should observer these general procedures and practices. The particular conditions of each site will
determine the applicability of such procedures.
WARNING! Risk of electrical shock. Can cause injury or death. Special care must be taken when working with
the batteries associated with this equipment. When the batteries are connected together, the battery-
terminal voltage will exceed 400VDC and is potentially lethal.
NOTE: All equipment not referred to in this manual is shipped with details of its own mechanical and electrical
installation.
NOTICE
Risk of incorrect input power connection. Can cause equipment damage.
The standard Liebert® UPS is suitable for connection to 60-Hz, 3-phase, 3-wire-plus-ground input power.
NOTE: Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer.
Connecting power before the commissioning engineer determines the system is properly installed may void the
warranty.
2.2 Preliminary Checks
Before installing the equipment, carry out the following preliminary checks:
•Visually examine the equipment for transit damage, both internally and externally. Report any damage to the
shipper and to your Vertiv representative immediately.
•Verify that the correct equipment is being installed. The equipment supplied has an identification tag on the
inside of the main door.
•Verify that the room in which the equipment will be installed satisfies the environmental conditions stipulated
in the equipment specification, paying particular attention to the ambient temperature and air-exchange
system.
2.3 Environmental Considerations
2.3.1 Battery Room
The Battery System is intended for indoor installation and should be located in a cool, dry, clean-air environment with
adequate ventilation to keep the ambient temperature within the specified operating range (see Specifications on page 29).
Temperature is a major factor in determining battery life and capacity. In a normal installation, the battery temperature
should be kept between 59 and 77°F (15°C and 25°C). Operating above this range will reduce the battery life; operating
below this range will reduce the battery capacity.
NOTE: Battery cabinets are convection-cooled. Keep batteries away from main heat sources, main air inlets and
similar heating, ventilation and cooling features. These can cause inconsistent temperatures in sections of the
batteries and reduce battery life or capacity.
2 Mechanical Installation 3

2.3.2 Storing the UPS and Batteries for Delayed Installation
If the system will not be installed immediately, store it indoors in a clean, dry, and cool location (see Specifications on page
29). The batteries’ requirements dictate the storage conditions. Unpack, install and charge batteries as soon as possible
after delivery.
NOTICE
Risk of failure to properly charge batteries. Can cause permanent damage to batteries and void the warranty.
Batteries will discharge during storage. Batteries must be recharged as recommended by the battery
manufacturer. A notice of “Charge Before Date” is affixed to each cabinet that has batteries inside. The “Charge
Before Date” is calculated based on storing the batteries at 77°F (25°C). Storage at a higher temperature will
increase the rate of self-discharge, which requires earlier recharge. Consult the battery manufacturer on how to
determine when the batteries need to be recharged.
2.4 Positioning
The cabinet is structurally designed to permit lifting from the base with a forklift, pallet jack or similar equipment.
Access to the power terminals, auxiliary terminal blocks and power switches is from the front and top.
Removable panels on the top are secured by screws. The door can be opened for access to the power connection bars,
auxiliary terminal blocks and power isolators. The front door can be opened 180degrees for service and installation.
2.4.1 Moving the Cabinets
Plan the travel route between the point of arrival and the unit’s final position to make sure that all passages are wide enough
for the unit and that floors are capable of supporting its weight. Check that doorways, lifts, ramps and so on are adequate
and that there are no impassable corners or changes in the level of corridors that would prevent passage.
Ensure that the cabinet weight is within the designated surface weight loading (kg/cm2) of any handling equipment. For
weights, see Specifications on page 29.
Move the battery cabinet with a forklift or similar equipment. The bottom structure of the cabinet will support the unit only if
the forks are completely beneath the unit.
Ensure that any equipment used in moving the cabinet has sufficient lifting capacity to transport the unit. Care must be
taken to protect the panels. Do not tilt the cabinet more than 15degrees.
Handling with straps is not authorized.
WARNING! Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or death.
Because the weight distribution in the cabinet is uneven, use extreme care while handling and transporting.
Take extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel. 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. For weights, see Specifications
on page 29.
2.4.2 Clearances
The battery system has no ventilation grilles at either side or at the rear. Leave a distance of 24in. (610mm) between the
top of the unit and any overhead obstacles or ceiling for service access and adequate air circulation. Clearance around the
front of the equipment should be sufficient to enable free passage of personnel with the doors fully opened.

2.5 System Configuration
A UPS system comprises a number of equipment cabinets, depending on the individual system design requirements. In
general, all the cabinets in an installation are the same height.
NOTE: If you are bolting cabinets together, remove the side panels before beginning installation.
• UPS with connected battery cabinets—The battery cabinets are connected to the UPSand internally wired.
The battery cabinets must be installed on the right of the UPS in a connected system. On 600-kVA and lower
models, the battery-wiring cabinet is a separate cabinet installed on the right side of the UPS between the UPS
and battery cabinets.
• Stand-alone, interconnected battery cabinets—Shown in Figure 2.3 on page8, with the battery-junction
cabinet on one end. The battery cabinets are interconnected with the battery-wiring cabinet, but are not
connected to the right side of the UPS. In this configuration, the battery-junction cabinet may be on either end
or between the battery cabinets.
• Stand-alone battery system—The battery-cabinet system stands alone. In this configuration, there is no
junction cabinet, and the battery cabinets are not connected to the UPS. Battery power cables are routed
directly to the DCbusbars in the UPS I/O cabinet.
NOTE: Make sure that you complete all cabinet and battery interconnections before making any power cabling
connections. The interconnects are very hard to access after the power wiring is complete. Refer to the submittal
drawings that shipped with the battery system, or contact your Vertiv sales representative for the drawings.
The detailed arrangement and cabinet dimensions for your Battery Cabinet is described in the installation drawings. Refer
to the appropriate illustrations for your unit included in submittal drawings that shipped with the battery system, or contact
