Self-diagnosis test

This test performs a failure diagnosis on the unit and performs a test to check for battery deterioration.
Use the procedure below to check whether a circuit failure has occurred inside the unit and whether
battery replacement is required.
This test is performed if the "Power" switch is ON or performed automatically (You do not have to
perform any special operations). Automatic test is performed once every 4 weeks after the unit is con-
nected to a commercial power source and power distribution begins.
If the battery is not charged for at least 24 hours, the self-diagnostic test is not executed immediately.
After charging is complete, it is automatically executed.
(1) When the self-diagnostic test is executed, the Battery Mode starts automatically (No beep
sounds). After the test is complete, the normal operation automatically starts.
(2) If an error message appears on the LCD:
Follow the directions for the solutions described earlier in this document.
* This test can also be run from the included UPS monitoring software.
