Vertiv Liebert GXT3 Series User Manual

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 GXT3 for 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.
NOTE: 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.
