1.Transfer the UPS to manual bypass by pressing the Standby/Manual Bypass button and holding it for about 2 seconds.

If manual bypass is not available, disregard the first step.

2.Press the Standby/Manual Bypass button twice within four seconds to shut down the UPS. The UPS will shut down about 30 seconds after the button is pressed.

Power to the connected loads is now Off.

4.6Disconnecting Input Power from the Liebert GXT3

1.Once the UPS has been shut down as detailed in 4.5 - Shut Down the Liebert® GXT3, disconnect the input cable plug.

2.Wait 30 seconds and verify that all indicators have turned Off and the fan has stopped; this indicates that the power-off is complete.

3.Turn the external battery cabinet breaker switch to the Off position if the UPS has an external battery cabinet.

After powering Off the UPS, the UPS ceases output and the load is powered Off.
