UPS will stop the output and enter a fault mode with 'EPO active' alarm. To recover
to normal operating state, below steps should be taken:
• Reconnect EPO connector
•
Clear the EPO alarm by selecting 'reset fault state in the LCD screen. The UPS
will go to bypass mode.
•
Press and hold the on/off button until the UPS output restarts.

to an external switch. The functions are programmable from the LCD screen. This

The dry output contact is a normally open relay interface. This is used to indicate
