ESCRIPTION 

Online 

This LED illuminates when the uninterruptible power supply is supplying utility power to 

the connected equipment. If not illuminated, the uninterruptible power supply is either not 

turned on, or is supplying battery power. When blinking, the uninterruptible power supply 

is running an internal self-test. 

AVR Trim 

This LED illuminates to indicate the uninterruptible power supply is compensating for a 

high utility voltage.  

AVR Boost 

This LED illuminates to indicate the uninterruptible power supply is compensating for a 

low utility voltage. 

On Battery  

This LED illuminates when the uninterruptible power supply is supplying battery power 

to the connected equipment.  

Overload 

This LED illuminates and the uninterruptible power supply emits a sustained alarm tone 

when the connected loads are drawing more than the uninterruptible power supply power 

rating (see Troubleshooting). 

Replace Battery/ 

Battery Disconnected 

Failure of a battery self-test causes the uninterruptible power supply to emit short beeps 

for one minute and this LED to illuminate (see Troubleshooting). 

This LED also flashes and a short beep is emitted every two seconds to indicate when the 

battery is disconnected (see Troubleshooting).

UNCTION

Power On 

Press this button to turn on the uninterruptible power supply. (Read on for additional ca-

pabilities.) 

Power Off 

Press this button to turn off the uninterruptible power supply. 

Self-Test  

Automatic: The uninterruptible power supply performs a self-test automatically when 

turned on, and every two weeks thereafter (by default). During the self-test, the uninter-

ruptible power supply briefly operates the connected equipment on battery. 

If the uninterruptible power supply fails the self-test, the replace battery LED illuminates 

and immediately returns to online operation. The connected equipment is not affected by a 

failed test. Allow the battery to recharge for 24 hours and perform another self-test. If it 

fails, the battery must be replaced. 

Manual: Press and hold the 

 button for a few seconds to initiate the self-test.
