5.5 External Battery Cabinet Installation
Optional Liebert external battery cabinets may be connected to the UPS to provide additional battery
run time. External battery cabinets are designed to be placed on one side of the UPS or stacked
beneath the UPS.
1. Visually inspect the external battery cabinet for freight damage. Report damage to the carrier
and your local dealer or Liebert representative.
2. For slide rail installations, first remove the top/side fin. Top/side fin slides forward and then lift
up to remove. Optional rack-mount handles are shipped with the external battery cabinet and
may be installed at this time if desired.
3. Securing hardware and slide rails are sold separately. Please contact your local dealer or Liebert
representative for these additional options and any assistance needed. Fasten the slides into
position with the screws per the instructions included with the slide rails.
4. Use the enclosed support bases for the tower option to prevent tip-over. One additional set of
support base extensions ships with each external battery cabinet.
5. Connect the supplied external battery cabinet cable to the rear of the external battery cabinet,
then to the rear of the UPS.
6. The UPS is now equipped with additional backup battery run time. For approximate battery run
times, refer to Table 5.
!
CAUTION
The external battery cabinet(s) are heavy (see 13.0 - Specifications). External battery
cabinets can be used in rack-mount or tower configuration. Take proper precautions when
lifting them.
!
CAUTION
Do not turn on (close) the battery cabinet circuit breaker yet. Complete the installation first.
NOTE
You must use the included configuration program to program the UPS for the number
of external battery cabinets connected. Instructions for the configuration program are in
7.0 - Configuration Program.
