Wiring Considerations

7.3Battery Wiring

The UPS may be supplied with battery cabinets or a rack-mounted battery system.

Power wiring to the battery cabinet connects positive, negative and ground power cables from the bat- tery cabinet to the associated UPS. Connection of the UPS to the battery cabinet serves to both charge and discharge the batteries (when needed). The battery disconnect (circuit breaker) requires a control cable. Except for interconnect wiring between multiple battery cabinets, power and control cables are field supplied. Refer to Figures 44 through 46.

! WARNING

A battery intercell connection on each tier of the Liebert battery cabinet is disconnected for safety during shipment. Do not complete these connections. A Liebert Global Services representative will complete these connections as part of start-up. An improperly installed unit can result in injury to personnel or damage to equipment.

! CAUTION

Be sure polarity is correct when wiring the battery cabinet to the connected equipment (positive to positive; negative to negative). If polarity is not correct, fuse failures or equipment damage can result.

! CAUTION

Cables between batteries and the UPS should be run in matched pairs, positive-with-negative, within each conduit or cable run. 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.

Call Liebert Global Services to schedule installation check-out, final battery intercell connections and start-up.

NOTE

A Liebert Battery Specialist can perform a detailed inspection of the entire battery system to ensure it meets current IEEE standards. This inspection service is recommended because batteries are a critical part of the UPS system.
