Installation

3.7Connecting Power Cables

1.Open the UPS input breaker.

2.Open the UPS bypass breaker.

3.Set the maintenance breaker to the Bypass position.

4.Remove the electrical connection protective panel, if installed, from the rear UPS panel.

5.Connect loads to the output terminals as illustrated in Figure 7.

6.Connect the utility to the corresponding input terminals (see Figure 7).

•If the bypass input is to be supplied separately, connect the bypass source to the corresponding bypass terminals.

•If the UPS is supplied from a single feed, connect the factory-supplied jumper between terminal UPS Input-BYP and Bypass Input-L1.

3.8External Battery Cabinets

Up to four external battery cabinets may be connected to the Liebert® GXT3-10000T220™. A cable to connect the battery cabinet and the Liebert GXT3-10000T220 is supplied with each battery cabinet.

Open the breaker before making battery cable connections.

Plug one end of this cable into the UPS and the other end into the battery cabinet—slotted fittings on each end ensure that the connection is properly made. If your UPS has an integrated battery, a compensating current may occur during connection. Once both ends of the cable have been connected, the circuit breaker on the external battery cabinet must be closed.
