THE OVERLOAD LED IS LIT AND THE UPS EMITS A SUSTAINED ALARM TONE

The UPS is overloaded.

 

The connected equipment exceeds the specified “maximum load” as de-

 

 

fined in Specifications at the APC web site, www.apc.com.

 

 

The alarm remains on until the overload is removed. Disconnect nonessen-

 

 

tial equipment from the UPS to eliminate the overload.

 

 

The UPS continues to supply power as long as it is online and the circuit

 

 

breaker does not trip; the UPS will not provide power from batteries in the

 

 

event of a utility voltage interruption.

 

 

If a continuous overload occurs while the UPS is on battery, the unit turns

 

 

off output in order to protect the UPS from possible damage.
