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 EXM 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 equipment damage.
Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer.
1.2 System Composition
A battery system can consist of a number of equipment cabinets, depending on the individual
system design requirements, e.g., Battery Cabinet. Refer to 3.0 - INSTALLATION DRAWINGS for
positioning the cabinets.
1.3 Preliminary Checks
Before installing the battery equipment, carry out the following preliminary checks:
• Remove all panels and visually inspect the cabinet, batteries, bus connections and cabinet for any shipping
damage. Exercise caution; voltage is present within the battery cabinet even before installation. If there are
signs of damage, do not proceed. Call Vertiv at 1-800-542-2378.
• 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.
1.4 Environmental Considerations
1.4.1 Battery Room

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°F 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).
1.4.2 Storing Batteries for Delayed Installation
If the battery system will not be installed immediately, it must be stored indoors in a clean, dry and
cool location. Batteries should be unpacked, installed and charged as soon as possible after
delivery.
NOTE
Keep batteries away from main heat sources, main air inlets, etc.

Vertiv | Liebert®EXM™EBC™480V User Manual | 7
NOTICE
Risk of failure to properly charge batteries. Can cause permanent damage to batteries and void the
warranty.
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.
1.4.3 Installation Considerations
Position—Refer to UPS manual (SL-26102 for 50-250kVA units) or submittals for complete
system line-up details. Liebert EXM Battery Cabinet(s) are designed to be located next to each
UPS module on the left side only and are also available in stand-alone configurations with painted
side panels. The front access design eliminates side and rear service clearance requirements.
Refer to Tables 13 and 14 for battery cabinet dimensions and weights.
Bolt-On Cabinets—Matching battery cabinets are designed to bolt only onto the left side of the
UPS module cabinet. Use bolts that ship with each unit to connect cabinet frames at posts, two
places in the front and two places in the rear.
Service Clearance—Allow front access to the battery cabinet at all times for maintenance and
service. 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. No service clearance is required on either
the side or rear. Clearance at the top of the cabinet is 24" (610mm).
Cables (50-250kVA Units)—Cables may be run between the cabinets through cutouts in the
top of the cabinet, eliminating the need for external conduit runs. Route cables before moving
cabinets into final position for bolting together. No top or bottom entry cables are required,
except for remotely located cabinets which require conduits.
Power terminals, auxiliary terminals blocks and circuit breakers 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 breakers. The front door
can be opened 180° for easier service and more flexibility in installation.
Software—To allow the UPS to accurately display the battery run time, the number of battery
cabinets must be noted when performing initial startup and setup using the configuration
software. This is to be performed by the Vertiv engineer when commissioning the unit.
Casters and Adjustable Stops—The adjustable stops are not designed to bear the full weight of
the cabinet. Lower the stops until they are finger-tight in contact with the floor. Then tighten a
small amount with a wrench (less than two turns) to give a good friction fit. When mounting the
battery cabinet on seismic stands, ensure that the casters are bearing the weight of the cabinet.

Vertiv | Liebert®EXM™EBC™480V User Manual | 8
1.5 Moving the Battery Cabinets
The battery cabinets should be moved with a forklift or similar equipment. The battery cabinet
has casters for movement over short distances. The bottoms of the battery cabinets are
reinforced to permit lifting by forklift to move them longer distances. The bottom structure will
support the unit only if the forks are completely beneath the unit.
The route 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 will support its weight
(for instance, check that doorways, lifts, ramps, etc., are big enough 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 13 through 14 for weight details.
Ensure that any lifting equipment used to move the battery equipment has sufficient lifting
capacity.
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.
Handling the unit with straps is not authorized.
1.5.1 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.
WARNING
Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or
death.
Exercise extreme care when handling battery cabinets to avoid equipment damage or
injury to personnel. The battery system cabinets weigh from 1820 to 4907 lb. (826 to
2226kg).
Locate center of gravity symbols and determine the unit’s weight before handling a
cabinet. Test lift and balance the cabinets before moving them. Maintain minimum tilt from
vertical at all times.
Read all of the following instructions before attempting to move, lift, or remove packaging
from unit, or prepare unit for installation.
AVERTISSEMENT
Le centre de gravité élevé de l’appareil présente un risque de renversement. Une mauvaise
manutention peut entraîner des dommages matériels, des blessures et même la mort.
Faites preuve d'une extrême prudence lors de la manutention des armoires ASC afin
d’éviter de les endommager ou de blesser le personnel. Le poids du module ASC varie entre

2.0 BATTERY INSTALLATION
2.1 Safety
Special care should be taken when working with the batteries associated with the Liebert EXM
Battery System equipment. When all the cells are connected together, the battery terminal
voltage will exceed 432VDC 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.
Lead-acid batteries can present a risk of fire because they generate hydrogen gas. In addition, the
electrical connections must be protected against accidental short circuits which can cause
sparks. 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.
Valve-regulated lead-acid (sealed-cell) batteries do require periodic maintenance. Although
maintenance of electrolyte levels is not required, visual inspections and checks of battery voltage
and connection resistance should be made.
NOTICE
Risk of equipment damage. Batteries should be cleaned with a dry cloth or a cloth lightly moistened with
water. Do not use cleaners on the batteries. Solvents can make the battery cases brittle.
WARNING
Risk of electrical shock and fire. Can cause equipment damage, personal injury or death.
Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from batteries.
AVERTISSEMENT
Risque de décharge électrique et d’incendie. Pouvant entraîner des dommages matériels,
des blessures et même la mort.
Le remplacement des batteries doit être effectué ou supervisé par des membres du
personnel dotés des compétences requises et connaissant les précautions à prendre. Le
personnel non autorisé ne doit pas avoir accès aux batteries.

Vertiv | Liebert®EXM™EBC™480V User Manual | 13
Because individual battery characteristics are not identical and may change over time, the UPS
module is equipped with circuitry to equalize battery cell voltages. This circuit increases charging
voltage to maintain flooded type battery cells at full capacity.
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 432VDC. 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 the 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.
2.1.1 Connecting the Batteries
If the Liebert EXM battery cabinet is installed on a raised floor, the battery power cables and
circuit breaker control cables may be routed to the UPS cabinet through the bottom of the
cabinet.
If the Liebert EXM battery cabinets are installed adjacent to one another on a solid floor, these
cables may be passed between the cabinets through the sides of the cabinets.
Intertray connections must be made before the battery cabinet may be used.
2.2 Power Connection
Depending on the site layout, the battery cabinets can be cabled as shown in Figure 1.
WARNING
Risk of electric shock, explosive reaction, hazardous chemicals and fire. Can cause
equipment damage, personal injury and death.
Do not use equalize charging with valve-regulated, lead-acid batteries, such as those in
Liebert Battery Cabinets. Refer to the battery manufacturer’s manual, available on the
manufacturer’s Web site, for specific information about equalize charging.
AVERTISSEMENT
Risque de décharge électrique, de réaction explosive, d’incendie et d’exposition à des
produits chimiques dangereux pouvant entraîner des dommages matériels, des blessures
et même la mort.
