4-2 Testing the UPS (executing the self-diagnostic test)

You can use the following procedure to check whether replacing the battery inside the UPS is required and
whether the internal circuit is at fault.
• If the battery is not fully charged, the self-diagnostic test is not executed immediately.
After charging is complete, it is automatically executed.
(1) Connect your PC and other devices to the UPS and then press the Start Switch to start operation.
(2) Press and hold the Start Switch of the UPS for at least 10 second.
Release the start switch when a beep sounds. The Battery mode starts for testing purpose.
(3) After the 10-second test is complete, the normal operation automatically starts.
(4) If there is no error, the Error Lamp and the Battery Replacement Lamp do not go on and a beep does not
sound.
(5) If the Error Lamp goes on and a beep sounds, take necessary countermeasures according to "1" of "C.
Failure (display and beep when a failure occurs in equipment)" on page 23.
(6) If the Battery Replacement Lamp goes on and a beep sounds, immediate battery replacement is neces-
sary as it indicates extreme battery deterioration. Replace the battery according to "6-2 Replacing the
battery" on page 29.
* You can execute this test from the attached UPS monitoring software. For more information, refer
