NSTALLATION
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
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. 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. Turn ON the battery breaker on the
rear of the external battery cabinet.
7. The UPS is now equipped with
additional backup battery run time.
For approximate battery run times,
refer to 13.0 - Battery Run Times.
!
CAUTION
The external battery cabinet(s) are heavy (see 11.0 -
Specifications). 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 8.0 - Configuration Program.
