Matching Battery Cabinets
Two sizes of optional battery cabinets are available. Refer to
to
The battery
cabinet cells range from 90 to 150 Ampere-hours. The same model battery cabinet may be paral-
leled in multiple cabinet strings for additional capacity. Battery capacity (in minutes) at your instal-
lation will depend on cabinet model, number of cabinets, and amount of critical load on the UPS.
1.
Handling.
The Battery Cabinet weighs 3000 to 4900 pounds. Forklift slots are provided for
easy handling.
2.
Cabinet Inspection.
Remove all panels and visually inspect the batteries, bus connections,
and cabinet for any damage.
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 1-800-542-2378.
3.
Battery Storage.
The batteries used in the Battery Cabinet have an excellent charge
retaining characteristic. The batteries can be stored 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 15°C to 25°C (59°F to 77°F). If the Battery
Cabinet is planned to be stored for longer than six months, contact Liebert Global Services for
recommended action.
4.
Installation.
The Battery Cabinet(s) can be located conveniently next to each UPS module.
The front-access-only-design eliminates side and rear service clearance requirements.
•
Environment.
Locate the Battery Cabinet in a clean, dry environment. Recommended
temperature range for optimum performance and lifetime is 20°C (68°F) to 25°C (77°F).
•
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 feet (1 meter) of clearance at the front of the cabinet when operating. Side and rear
panels do not require service clearance.
•
Side Panels.
Remove protective side panels to connect cabinets together. Panels are
retained at the bottom with three screws.
•
Shield Plate (100-225 kVA only).
The shield plate inside the Battery Cabinet should be
on the side toward the UPS module for proper UPS airflow. Move the shield if required by
your Battery Cabinet location.
•
Cables.
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.
Remove top panels for access, if required. No
top or bottom entry cables are required, except for remotely located cabinets which require
conduits. Refer to
through
•
Built-In Cabinets.
Matching Battery Cabinets are designed as a bolt-on section to the side
of the UPS module cabinet. Use bolts (3/8"-16 x 1-1/4") to connect cabinet frames at posts,
two places front and two places rear. Brackets are provided to make rear connections easier
from inside the cabinet.
6.3
Non-Standard Batteries

tery disconnect switch with overcurrent protection is required per the National Electrical Code.
