APP-A. Troubleshooting
Troubleshooting procedures give simple instructions in determining UPS malfunctions. Start the
troubleshooting procedure if you witness any alarm indication.
Alarm
The UPS has an audible alarm. When different situations occurred, UPS will alert users with display
and buzzer.
Battery-mode (Slow alarm)
During battery mode, the alarm will beep every 2 seconds. The alarm will stop when UPS return to
Line-mode.
Battery-Low (Rapid alarm)
During Battery-low (less than 30%), the UPS will beep every 0.5 seconds. The alarm will stop when UPS
shutdown or returns to Line-mode.
Overload (Constant alarm)
When UPS operating with load exceeded its maximum capacity, UPS will emit a continuous alarm to
warn an overload condition. UPS will automatically turn off to protect your essential load. Please consider
remove or shutdown less-essential loads.
Silencing Alarm
Here is the instruction to mute the active alarm or future alarm notification:
Note
: During battery-mode, if the battery is low on power, the alarm will sound regardless of
silent-mode enable/disable.
If troubleshooting does not include or resolve your situation, feel free to contact for technical
assistance.
