IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation of your
Liebert® large system, three-phase UPS battery cabinet and accessories. Read this manual
thoroughly, paying special attention to the sections that apply to your installation, before working
with the battery system. Retain this manual for use by installing personnel.
WARNING
Risk of electrical shock. Can cause personal injury and death.
Special safety precautions are required for procedures involving handling, installation and
maintenance of the UPS system. Only properly trained and qualified personnel wearing
appropriate personal protective equipment should be involved in installing the Liebert®
battery system or preparing the system for installation.
Special care must be taken when working with the batteries associated with this
equipment. When connected together, the battery terminal voltage will exceed 400VDC
and is potentially lethal. Be constantly aware that the battery system contains high DC as
well as AC voltages. Check for voltage with AC and DC voltmeters before making contact.
Observe all DC safety precautions before working on or near the DC system.
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.
The following precautions must be observed when working on batteries:
• 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 whether the battery is grounded. If it is 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.
If a battery leaks electrolyte, or is otherwise physically damaged, it must be replaced, stored
in a container resistant to sulfuric acid and disposed of in accordance with local regulations.
If electrolyte comes into contact with skin, the affected area should be washed immediately
with water.
WARNING
Risk of electric shock, explosive reaction, hazardous chemicals and fire. Can cause
equipment damage, personal injury and death.
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 dispose of a battery in a fire. The battery may explode.
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin
and eyes. It is toxic.

1.0 MECHANICAL INSTALLATION
1.1 Introduction
This following section describes the requirements that must be taken into account when
planning the positioning and cabling of the Liebert® battery equipment.
This chapter is a guide to general procedures and practices that should be observed by the
installing engineer. The particular conditions of each site will determine the applicability of such
procedures.
NOTICE
Risk of improper startup. Can cause voiding of warranty and equipment damage.
Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer.
1.2 Preliminary Checks
Before installing the battery equipment, perform the following preliminary checks:
• Visually examine the equipment for transit damage, both internally and externally. Report any damage to
the shipper immediately.
• Verify that the correct equipment is being installed. The equipment supplied has an identification tag
inside the main door.
• Verify that the battery room satisfies the environmental conditions stipulated in the equipment
specification, paying particular attention to the ambient temperature and air exchange system.
1.3 Environmental Considerations
1.3.1 Battery Room
Batteries should be installed in an environment where the temperature is consistent and even
over the whole battery. Temperature is a major factor in determining the battery life and capacity.
Typical battery manufacturer performance data are quoted for an operating temperature
between 68 and 77°F (20 and 25°C). Operating above this range will reduce the battery life while
operation below this range will reduce the battery capacity.
Battery Temperature
In a normal installation, the battery temperature should be kept between 59 and 77°F (15°C and
25°C).
1.3.2 Storage for Delayed Installation
If the equipment will not be installed immediately, it must be stored indoors in a clean, dry and
cool location (see Environmental Parameters in Table 4). If the UPS includes batteries, either
internally or in a battery cabinet, the batteries’ requirements will dictate the storage conditions.
Batteries should be unpacked, installed and charged as soon as possible after delivery.
NOTICE
Risk of failure to properly charge batteries. Can cause permanent damage to batteries and void the
warranty.
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 either battery life or capacity.

Vertiv | Liebert®Large System Installation Manual | 5
Batteries will self-discharge during storage. Batteries must be recharged as recommended by the battery
manufacturer.
A notice of “Charge Before Date” is affixed to each unit that has batteries inside. The “Charge Before
Date” is calculated based on the batteries being stored at 77°F (25°C). Storage at a higher temperature
will increase the rate of self-discharge, requiring earlier recharge. Consult the battery manufacturer on
how to determine when the batteries need to be recharged.

Vertiv | Liebert®Large System Installation Manual | 6
1.4 Positioning
The cabinet is structurally designed to handle lifting from the base.
Power terminals, auxiliary terminals blocks and power switches are accessed from the front and
top.
Removable panels on the top are secured to the chassis by screws. The door can be opened to
give access to the power connections bars, auxiliary terminal blocks and power isolators. The
front door can be opened 180° for easier service and more flexibility in installation.
1.4.1 Moving the Cabinets
The route to be traveled between the point of arrival and the unit’s installation location must be
planned to make sure that all passages are wide enough for the unit and that floors are capable of
supporting its weight (for instance, check that doorways, lifts, ramps, etc., are adequate and that
there are no impassable corners or changes in the level of corridors).
Ensure that the cabinet weight is within the designated surface weight loading (kg/cm2) of any
handling equipment. See Tables 4 and 7for weight details.
Ensure that any lifting equipment used to move the battery equipment has sufficient lifting
capacity.
Battery system equipment can be handled by a forklift or similar equipment.
Because the weight distribution in the cabinet is not symmetrical, use extreme care during
handling and transporting.
When moving the unit by forklift, care must be taken to protect the panels. Do not exceed a 15° tilt
with the forklift. Bottom structure will support the unit only if the forks are completely beneath the
unit.
Handling the unit with straps is not authorized.
The cabinet with top-terminal and front-terminal batteries ships with extra bolts installed on the
interior doors. Once the cabinet is in the final position, these bolts can be removed. See Figures 1
and 2.
WARNING
Risk of heavy unit falling over. Can cause equipment damage, injury and death.
Exercise extreme care when handling battery cabinets. The battery system cabinets weigh
from 3155 to 9100 lb. (1431 to 4128kg).
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 cabinets are intended for forklift use. Base slots will support the unit
only if the forks are completely beneath the unit.

1.4.2 Clearances
The Liebert® battery system has no ventilation grilles at either side or at the rear of the battery
system equipment. It is important to leave a distance of 24" (610mm) between the top of the
cabinet and the ceiling of the room where it is installed to permit adequate circulation of air
coming out of the unit and for service access.
Clearance around the front of the equipment should be sufficient to enable free passage of
personnel with the doors fully opened.
1.4.3 Raised Floor Mounting
If the equipment is to be placed on a raised floor, it should be mounted on a pedestal suitably
designed to accept the equipment point loading. Refer to the base view to design this pedestal.
1.5 System Composition
A battery system can consist of a number of equipment cabinets, depending on the individual
system design requirements, e.g., Battery Cabinet, Junction Cabinet. Refer to 3.0 -
INSTALLATION DRAWINGS for the positioning of the cabinets described below.
NOTE
A junction cabinet is required for Liebert® NXL™ units rated 500kVA and above except for stand-
alone individual battery systems.

2.0 BATTERY INSTALLATION
2.1 Safety
Special care should be taken when working with the batteries associated with the Liebert®
battery system equipment. When all the cells are connected together, the battery terminal
voltage will exceed 400V and is potentially lethal. A primary safety consideration is to install the
battery equipment in an isolated area, accessible only to properly trained and qualified
maintenance personnel.
WARNING
Risk of electric shock. Can cause equipment damage, personal injury and death.
Hazardous battery voltage present behind covers. No user-serviceable parts are located
behind covers that require a tool for removal. Only properly trained and qualified service
personnel are authorized to remove such covers or perform installation or maintenance.
The following general battery safety precautions and warnings must be observed at all
times:
• A battery can present risk of electric shock or burn from high short circuit currents.
• When connected in a string, the voltage will exceed 400VDC. This voltage is
potentially lethal. Always observe high-voltage precautions.
• Eye protection must be worn to prevent injury from accidental electrical arcs.
• Remove rings, watches, necklaces, bracelets and all other metal objects.
• Use only tools with insulated handles.
• Wear appropriate personal protective equipment when handling batteries.
• If a battery leaks electrolyte or is otherwise physically damaged, it should be placed in
a container resistant to wire and disposed of in accordance with local regulations.
• If electrolyte comes into contact with skin, the affected area should be washed
immediately with plenty of clean water.
• Batteries must always be disposed of according to local environmental laws.
• When replacing batteries, use the same number and type that were originally fitted.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if the battery is grounded. If it is grounded, remove source of ground.
Contact with any part of a grounded battery can result in electrical shock.
• Battery support tray must be used whenever a battery tray is being pulled out.
