Battery Cabinets - Liebert Series 600T Installation Manual

6.2 Battery Cabinets

Optional battery cabinets are available from
Liebert and other qualified vendors. Consult your
submittal package for details.
The same model battery cabinet may be paralleled
in multiple cabinet strings for additional capacity.
Battery capacity (in minutes) at your installation
will depend on cabinet model, number of cabinets,
and amount of critical load on the UPS.
1. Handling. The Battery Cabinet weighs up to
5100 pounds. Fork lift slots are provided in the
base of 100-225 kVA cabinets for easy
handling. Fork lift forks or a pallet jack can be
used between the casters of the 65 and 80 kVA
battery cabinets.
2. Cabinet Inspection. Remove all panels and
visually inspect the batteries, bus connections,
and cabinet for any damage. If any foam blocks
were placed between shelves to restrain
movement during shipment, remove them now.
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 retain their charge well. 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 must be stored for longer
than six months, contact Liebert Global
Services.
4. Installation. The Battery Cabinet(s) can be
located conveniently to the left side of the 65-
225 kVA UPS module. The front-access-only-
design eliminates side and rear service
clearance requirements.
5. Re-Installation. If it later becomes necessary
to move the Battery Cabinet to another
location, contact Liebert Global Services to
inspect the internal battery hold-down straps.
6. Environment. Locate the Battery Cabinet in
a clean, dry environment. Recommended
temperature range for optimum performance
and lifetime is 20-25°C (68-77°F).

7. 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.
8. Side Panels. Remove protective side panels to
connect battery cabinets together. Do not
remove the shield plate, explained below.
9. Shield Plate. The shield plate in 125 kVA
Battery Cabinets should be on the side toward
the UPS system. Move the shield if required by
your Battery Cabinet location.
10. Cables. Cables may be run between battery
cabinets through cutouts in the top of the
cabinets, eliminating the need for external
conduit runs. Route cables before moving
cabinets into final position for bolting
together. Remove top panels for access. Refer
to Figures 16 and 17 or your submittal
drawings for instructions on wiring cabinets in
parallel.
11. Grounding. The battery cabinets have ground
studs near the bus bar connections. Use an
equipment grounding conductor to connect the
lugs of the cabinets together and to connect the
cabinets to the ground bus bar in the UPS
module.
CAUTION
Cables between batteries and modules
should be run in matched pairs, positive-
with-negative. Grouping like-polarity
cables together (i.e. positive-with-positive
and negative-with-negative) can cause
stress or damage to the cables, conduit or
buswork.
