2.4.2 Rack Installation
The Liebert GXT4 UPS and external battery cabinets (EBC), when installed in a rack enclosure, must
be supported by a shelf or rack-mount rails. The Liebert GXT4 UPS and EBC units ship with all
required hardware to allow rack-mount installation (not included with “E” models). Because different
rack-mount options install differently, refer to the installation instructions provided with the rack
mount kit being used.
2.5 Cable Connection
The Liebert GXT4 rear panel has an input receptacle and output receptacles. Refer to 1.3.2 - Rear
Panel Features for details. The battery cables are supplied with the battery cabinet.
2.5.1 Connecting to AC Mains and Loads
The specification of input circuit breaker on the rear panel of the UPS is given in Table 2.
NOTE
Ensure that all the loads are turned Off.
Prepare an input power supply that is properly protected by a circuit breaker in accordance
with national and local electrical codes. The wall receptacle must be grounded.
