6.2.2Battery Mode Shutdown

Battery Mode Shutdown permits shutting down the UPS by turning off the rectifier, inverter and static switch so that there is no power to the load when the UPS is On Battery. The auxiliary power for the UPS will still be active.

Battery Mode Shutdown can be performed locally or remotely:

•Local Battery Mode shutdown can be performed by shorting the pins in Set 4.

•Remote Battery Mode Shutdown can be performed using a switch connected to the pins in Set 4 and mounted at remote location.

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 (+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.

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.

6.2.3On Battery

On Battery signal is a Normally Open (NO) dry contact. When the UPS is supplying output power from the battery this dry contact will be closed.

6.2.4Low Battery

Low Battery signal is a Normally Open (NO) dry contact. When the UPS is supplying output power from the battery and has reached the Low Battery Warning time selected in the configuration program, this dry contact will be closed.

NOTE

The rated values for the dry contacts are:

•Rated Voltage: 30V (AC or DC)

•Rated Current: 300mA
