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.
