Rackmount Setup

CAUTION: The cabinet is heavy (see page 62): 1) Dell strongly recommends to remove the battery tray from the UPS before lifting. 2) Lifting the cabinets into the rack requires a minimum of two people.

CAUTION: Removing the batteries should be performed or supervised by personnel knowledgeable about batteries and the required precautions. Keep unauthorized personnel away from batteries.

CAUTION: If installing an optional EBM, install the EBM directly below the UPS.

NOTE: Mounting rails are required for each individual cabinet.

To install the UPS and optional EBM in a rack:

1Remove the internal battery trays from the UPS:

Loosen the thumbscrew on the battery retaining bracket and remove (see Figure 9).
