5.4External 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. The run time is limited to a maximum of four (4) hours.

! CAUTION

The external battery cabinet(s) are heavy (see 12.0 - Specifications). External battery cabinets can be used in rack-mount or tower configuration. Take proper precautions when lifting them.

1.Visually inspect the external battery cabinet for freight damage. Report damage to the carrier and your local dealer or Liebert representative.

2.The rack-mount handles are shipped with the external battery cabinet and may be installed at this time (see 5.3 - Rack-Mount UPS Conversion and Installation).

3.Fixed rails and securing hardware ship with the external battery cabinet. Fasten the fixed rails into position with the screws per the instructions included with the UPS. Repeat

Steps 1 through 10 from 5.3 - Rack-Mount UPS Conversion and Installation.

4.Use the support bases included with the UPS for the tower option to prevent tip-over. One additional set of support base spacers 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, as shown at right.
