Communication

Activation of the Battery Mode Shutdown will be logged as an event in the event history log.

NOTE

Remote Power Off will be performed by NO contact.

The current limited source for the optocoupler (+12VDC, 50mA) will be available from UPS.

The connection to the Liebert® GXT3for remote connection will be via terminal block connector.

Battery Mode Shutdown wiring must conform to all national, regional and local wiring codes and laws.

This signal must last for 1.5 seconds or longer.

A battery shutdown signal will not cause an immediate shutdown. It will start a 2-minute shutdown timer. This timer cannot be stopped once triggered. If the utility power returns during this countdown, the Liebert GXT3 will still shut down and must remain shut down for 10 seconds. Whether the UPS turns back On when the power is restored depends on the auto-restart setting.
