Replace Battery 
 
Failure of a battery self-test causes the UPS to emit short beeps for one 
minute and the replace battery LED illuminates. Refer to Trouble-
shooting
 in this manual. 
Battery 
Disconnected 
 
The replace battery LED flashes and short beep is emitted every two 
seconds to indicate the battery is disconnected. 
Automatic Self-Test 
The UPS performs a self-test automatically when turned on, and every 
two weeks thereafter (by default). 
During the self-test, the UPS briefly operates the connected equipment 
on battery. 
If the UPS fails the self-test, the replace battery LED 
 lights and 
immediately returns to online operation. The connected equipment is 
not affected by a failed test. Recharge the battery for 24 hours and per-
form another self-test. If it fails, the battery must be replaced. 
Manual Self-Test 
Press and hold the 
 button for a few seconds to initiate the self-test. 
On Battery Operation 
The Smart-UPS switches to battery operation automatically if the utility power fails. While running 
on battery, an alarm beeps four times every 30 seconds. 
Press the 
 button (front panel) to silence the UPS alarm (for the current alarm only). If the utility 
power does not return, the UPS continues to supply power to the connected equipment until the bat-
tery is exhausted. 
If PowerChute
®
 is not being used you must manually save your files and turn off the computer before 
the UPS fully discharges the battery.
