6.2 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.
The external battery cabinet frame and battery kits are shipped separately. This 4U cabinet arrives
without internal batteries to lighten the cabinet for easier installation. Once the cabinet has been
placed in its final floor or rack position, the internal batteries may be installed.
When the external battery cabinet is received, it should be inspected for freight damage. Report dam-
age to the carrier and your local dealer or Liebert representative.
To install an external battery cabinet:
1. For slide rail installations, first remove the top/side fin by sliding it forward and lifting it up.
Optional rack-mount handles are shipped with the external battery cabinet and may be installed
now. (Securing hardware and slide rails are sold separately. Please contact your local dealer or
Liebert representative for these additional options and any assistance needed.)
2. Fasten the slides into position with the screws according to the instructions included with the
slide rails.
3. Use the enclosed support bases for the tower option to
prevent the assembly from tipping over. One additional set
of support base extensions ships with each external battery
cabinet.
4. Install the two battery packs and secure with the two
brackets supplied.
5. Connect the two slotted battery cables.
6. Attach the battery cover plate and the two front bezels.
7. Connect the supplied external battery cabinet cables to
either set of connectors on the rear of the external battery
cabinet, then to the rear of the UPS.
8. The UPS is now equipped with additional backup battery
run time. For approximate battery run times, refer to Table
6 - Battery run times in this manual.
9. Do NOT turn on the battery cabinet circuit breaker at this
time. Please complete the remainder of the installation first.
!
CAUTION
The external battery cabinet(s) are heavy (see 14.0 - Specifications). External battery
cabinets can be used in rack-mount or tower configuration. Take proper precautions when
lifting them.
!
CAUTION
Verify that the battery cabinet circuit breaker is in the OFF position. Do no energize the
battery cabinet at this time. When installation is complete, you will be instructed to turn on
the circuit breaker.
NOTE
UPS automatically detects the number of standard
batteries that are connected. The configuration program
may be used to set up the UPS for operation with non-
standard external batteries. Instructions for using the
configuration program follow in 8.0 - Configuration
Program.
