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 all on one side of the UPS or stacked beneath the
UPS. There is no limit to the number of external battery cabinets that can
be used but each cabinet will increase the battery recharge time.
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 han-
dles 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 cab-
inet cable to the rear of the external bat-
tery cabinet, then to the rear of the UPS.
6. Turn ON the battery breaker on the
rear of the external battery cabinet.
7. The UPS is now equipped with addi-
tional backup battery run time. For
approximate battery run times, refer to
the Battery Run Times charts in this
manual.
!
CAUTION
The external battery cabinet(s) are heavy (see
Specifications section). External battery cabinets can be
used in rack-mount or tower configuration. Take proper
precautions when lifting them.
NOTE
You must use the included Configuration Program to specify
the number of external battery cabinets connected to the UPS.
For more information, see Configuration Program on
page 22.
