2.5 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 in a tower configuration
or stacked beneath the UPS in a rack configuration.

1. Inspect the external battery cabinet for freight damage. Report damage to the carrier and your local
dealer or Emerson representative.
2. Optional rack-mount hardware is shipped with the external battery cabinet and may be installed at this
time if desired.
• Securing hardware and slide rails are sold separately. Please contact your local dealer or Emerson
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.
3. 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.
4. Verify the External Battery Cabinet breaker is in the Off position.
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 the External Battery Cabinet breaker to the On position.
WARNING
Risk of electric shock. Can cause injury or death.
Disconnect all local and remote electric power supplies before working within.
Ensure that the Liebert GXT4 is shut down and power has been disconnected before beginning
any work on or in the unit.
CAUTION
The external battery cabinet(s) are heavy (see Table 8-3). Take proper precautions when lifting
them.
