Automatic Self-Test 
The UPS performs a self-test automatically when turned on, and 
every two weeks thereafter (by default). Refer to User Configur-
able Items
 for details on changing the default interval. 
Automatic self-test eases maintenance requirements by eliminating 
the need for periodic manual self-tests. During the self-test, the 
UPS briefly operates the connected equipment on battery. If the 
UPS passes the self-test, it returns to online operation. 
If the UPS fails the self-test, the UPS lights the replace battery 
LED 
 and immediately returns to online operation. The con-
nected equipment is not affected by a failed test. Recharge the bat-
tery for 24 hours and perform another self-test. If it fails, the bat-
tery must be replaced. 
Manual Self-Test 
Press and hold the 
 button for a few seconds to initiate the self-
test.

During normal operation, the UPS monitors the utility power and delivers power to the connected 
equipment. If your system is experiencing excessive periods of high or low voltage, have a certified 
electrician check your facility for electrical problems. If the problem continues, contact the utility 
company for further assistance. 
Online 
 
The online LED illuminates when the UPS is supplying utility 
power to the connected equipment. If the LED is not lit, the UPS is 
either not turned ON, or is supplying battery power. The UPS 
sounds an alarm—four beeps every 30 seconds. 
Utility Voltage 
 
The UPS has a diagnostic feature that displays the utility voltage. 
Plug the UPS into the normal utility power. 
Press and hold the 
 button to view the utility voltage bar graph 
display. After a few seconds the five-LED display on the right of the 
front panel shows the utility input voltage. Refer to the figure at left 
for the voltage reading (values are not listed on the UPS). 
 
The UPS starts a self-test as part of this procedure. The self-test does not affect 
the voltage display. 
 
The display indicates the voltage is between the displayed value on 
the list and the next higher value. For example, with three LEDs lit 
on the 120V model, the input voltage is between 115 and 134 VAC. 
If no LEDs are lit and the UPS is plugged into a working, utility 
power outlet, the line voltage is extremely low. 
If all five LEDs are lit, the line voltage is extremely high and should 
be checked by an electrician.
