If the input utility is present, the UPS’s controls will remain active; however, the output will be turned Off. To
remove all power from the UPS, the external feeder breaker should be opened.

Auto Restart
When the main and bypass sources fail, the UPS draws power from the battery system to supply the load until
the batteries are depleted. When the UPS reaches its end of discharge (EOD) threshold, it will shut down.
The UPS will automatically restart and enable output power:
•
after utility power is restored
•
if “Auto Recovery after EOD Enabling” is enabled in the UPS configuration (set by factory or by Vertiv
™
Services)
•
after the “Auto Recovery after EOD Delay Time” expires (the default delay is 10 minutes)
During the auto recovery delay, the Liebert
®
EXM will be charging its batteries to provide a safety margin for equipment
shutdown if input power fails again.
If the “Auto Recovery after EOD Enabling” feature is disabled, the system must be restarted manually.
