Installation

2.5Cable Connection

The Liebert® GXT3™ rear panel has an input cable and plug, output receptacles and output cable(s) (Output cables are on GXT3-3000 models only). Refer to 1.3.2 - Rear Panel Features for details. The battery cables are supplied with the battery cabinet.

2.5.1Connecting Input Plug and Loads

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.

The plug on the power supply cord is intended to serve as the disconnect device. The socket-outlet must be installed near the equipment and must be easily accessible.

Emerson recommends installing an upstream circuit breaker of the same series as the Liebert GXT3’s input circuit breaker.

The specification of input circuit breaker on the rear panel of UPS is given in Table 2.

1. Plug all loads into the output receptacles on the rear panel of the Liebert GXT3.

NOTE

1. Distribute loads evenly across all receptacles to prevent overloading individual receptacles.

2.Output cable length should not exceed 32.8 ft (10m).

3.Insert the input plug of Liebert GXT3 into the input power connection.

2.5.2Connecting Battery Cables

1.Switch Off the input breaker of the battery cabinet.

2.Take out the battery cable included with the battery cabinet.

3.Connect one end of the battery cable to the external battery connector on the rear panel of the UPS, and connect the other end to any battery port on the rear panel of the battery cabinet.

4.Switch On the battery breaker on the rear of the external battery cabinet.

5.Use the Configuration Program included with the UPS to specify the number of external battery cabinets connected to the Liebert GXT3. See Table 15 for approximate battery run times.
