Why is my Eaton Ellipse PRO 850 running on battery when AC power is on?

If AC power is available but your Eaton UPS operates on battery power, the circuit breaker located at the rear of the UPS might have been tripped due to an overload. Try resetting the circuit breaker to restore normal operation.
