6.3. UPS Working Modes
Normal Mode
After turning it on, and if the utility power supply is normal, the UPS will work in

(online mode) and convert the mains input current into a clean and
stable AC output. In this mode, the power flows through the battery and supplies the
connected devices as shown on the LCD.
IMPORTANT!

beeps. Then the „FAULT” LED indicator shines, and the device enters
Bypass Mode

reduce the load
below 100%
.
When the battery condition is abnormal, the „BATTERY” LED indicator blinks. Please

power supply power losses.
