alarms represent normal or correctable operational alarms. Category two alarms are
sounded in the event of abnormal operation.

Notifies the user that the SG UPS is configured with the optional battery
pack and is in BATTERY MODE.
- - - - - = SG UPS IS IN BATTERY MODE
b. A continuous short beep.
The SG UPS is operating from battery and is in a LOW BATTERY operation.
- - - - - - - - = SG UPS IS IN A LOW BATTERY CONDITION
c. One long beep prior to a short beep.
The SG UPS is in an OVER LOADED, OVER CREST CONDITION. Remove
some load from the UPS output to correct this condition.

2. Category two alarms:
a. Three short beeps indicate the SG UPS output voltage is out of proper
operating range.
- - - = SG UPS OUTPUT VOLTAGE IS OUT OF PROPER RANGE.
b. Four short beeps indicate the SG UPS output frequency is out of proper
operating range. The UPS must be repaired.
- - - - = SG UPS OUTPUT FREQUENCY IS OUT OF PROPER RANGE.
c. Five short beeps indicate the SG UPS is in an over-temperature condition.
Check for proper UPS cooling fan operation or blockage.
- - - - - = SG UPS INTERNAL TEMPERATURE IS TOO HIGH.
d. Should the internal POWER UP SELF-TEST fail, the SG UPS will sound the
following alarms denoting the failure mode:
* A continuous rapid beeping for about 5 seconds, then the SG UPS shuts
down - The UPS output voltage is out of range.
