4.4EXTERNAL 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. There is no limit to the number of external battery cabinets that can be used but each cabinet will increase the battery recharge time.

! 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.

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.

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.
