6.7 UPS Reset Procedures after EPO
After shutting down the UPS through EPO or reasons of UPS fault, clear the fault according to the alarm message displayed
on TOUCH SCREEN screen. Then carry out the following reset procedures to make UPS resume normal operation.
After confirming the fault has been cleared and no remote EPO signal is received, the user can carry out the following
procedures:
1. Click the Reset FAULT button (Refer to Operator Controls), the system will exit the EPO/abnormal OFF state,
and the alarm indicator flashes in red color.
2. After the rectifier start-up is finished, normally start the UPS according to Transfer from Normal Mode to
Bypass Mode.

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.

6.8 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 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.
