normally, but it works in the
battery mode and the buzzer
beeps intermittently.

circuit are in good condition;
2. Check if the displayed input voltage amplitude or
frequency of mains on the LCD is beyond the allowable
range of UPS;
3. Check if the mains input breaker is disconnected, if yes,
please close the breaker again.
After installing UPS,

fuse the fuse or cause
tripping operation.
