2.5 Cable Connection
The Liebert GXT4 rear panel has an input cable and plug, output receptacles and output cable(s)
(Output cables are on GXT4-3000 models only). 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 UPS is given in Table 2..
Liebert GXT4 models 700-1500VA and 2000VA have three groups of outlets as shown in Figure 2.
One group is always On; the other two groups may be controlled with either programmed responses or
over an SNMP network. The 3000VA GXT4 UPS has four groups of outlets: two groups are not
controlled (always On), and two groups may be controlled with either programmed responses or over
an SNMP network.
Verify that the equipment is plugged into the appropriate outlets if any outlets will be controlled with
these features.
1. Plug equipment into the appropriate output receptacles on the rear of the Liebert GXT4.
2. Plug the input receptacle of the Liebert GXT4 into the input power connection.
3. Install the two cable strain relief fixtures to secure either the input or output cables to prevent
accidental disconnection.
a. Insert one end into the provided holes on the rear of the unit.
b. Place the power cord(s) inside the loop.
c. Tighten the loop around the cables.

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.
Emerson recommends installing an upstream circuit breaker of the same series as the Liebert
GXT4’s input circuit breaker.
