3. After pressing the EPO button, if the mains input is switched off, the UPS will shut down completely.
When the mains input returns, the UPS will start up on bypass. There will be power at the output terminals
of the UPS.
Warning
If the maintenance bypass switch Q3 is closed and the UPS has input power, it means UPS has outputs.
5.8 Automatic Restart
In the case of a mains failure, the UPS draws power from the battery system to supply the load until the
batteries are depleted. When the UPS reaches its EOD threshold, it will shut down.
The UPS will automatically restart and enable output power only when the following conditions are met:
1. If Auto Recovery after EOD Enabling is enabled.
2. After the Auto Recovery after EOD Delay Time expires (the default delay is 10 minutes), the UPS
restarts bypass, then inverter. During the automatic recovery delay, the UPS will charge its batteries to
provide a safety margin for equipment shutdown if input power fails again.
Note
During the automatic restart process, manual startup is disabled. Automatic restart must be set by Vertiv's
authorized service engineer through Vertiv setting software.
