EPO

Only use the EPO button in case of emergency.

It can be configured whether, when the EPO is activated, the UPS should:

  • turn off the rectifier, inverter, charger, and static bypass and stop supplying the load immediately (default), or

  • transfer to static bypass mode and continue supplying the load.

DANGER
hazard of electric shock, explosion, or arc flash
The UPS control circuit will remain active after the EPO has been pushed if utility/mains is available.
Failure to follow these instructions will result in death or serious injury.
