What to do when the "Overload LED" on a Smart-UPS is illuminated?

Issue:
When loads exceed the UPS's rated VA(volt-amp) or Watt capacity, the overload LED will illuminate and the UPS will emit a continuous tone. The alarm stays on until the overload is removed.

Product Line:
Smart-UPS

Environment:
All models, All Serial Numbers

Cause:
Normal Operation

Resolution:
Disconnect nonessential load equipment from the UPS to eliminate the overload.

If the overload is severe, the input circuit breaker may trip (the resettable center plunger of the circuit breaker pops out). Disconnect nonessential load equipment from the UPS to eliminate the overload and press the plunger back in.

If there is AC power and the overload is not so severe as to trip the UPS circuit breaker, then the loads will still be powered. If the circuit breaker trips or the UPS attempts to transfer to battery in an overload condition, the load's power will be shut off. Turn the UPS off then back on to power the loads.

If the Overload LED remains illuminated even without any load plugged into the UPS, the UPS has most likely sustained a surge or fault, and will need to be replaced. Contact APC Technical Support to resolve the problem.
