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 19). 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.
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.
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.

Mechanical Installation
Vertiv Large System, 3-Phase UPS Battery System Installation Manual 4
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 19 and 22 for 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.
