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.
