Why is my MGE UPS Systems Ellipse 1000 operating on battery even when AC power is available?

If AC power is available but your MGE UPS Systems UPS is operating on battery power, it could be because the circuit breaker located under the UPS has been tripped by an overload. Try disconnecting some equipment and reset the circuit breaker by pressing the button.
