Any Mode Battery Mode Shutdown Shutdown

The purpose of Any Mode Shutdown is to shut down the UPS output by turning Off the rectifier, inverter and static switch so that there is no power to the loads.

Any Mode Shutdown can be operated locally or remotely:

Local Any Mode Shutdown can be performed by shorting the pins in Set 3.

Remote Any Mode Shutdown can be performed using a switch connected to the pins in Set 3 and mounted at a remote location.

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

NOTE

Remote Power Off will be performed either by NO or NC contact of Any Mode Shutdown. The current limited source for this optocoupler (+12VDC, 50mA) will be available from UPS. The connection to UPS for remote connection will be via terminal block connector.

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

! WARNING

When the Auto-enable output option is selected and the UPS output is disabled using the pins in Set 3, the Liebert GXT3’s output can turn On automatically and without warning if the connection to the pins in Set 3 is changed.
