Abnormal
Description & Checkpoint
Solution
(6) Fans cannot
work while
UPS is on.
The fuses positioned behind PCB holder
have been blown or are not installed well.
Replace the fuses or install
them well.
Abnormal voltage output in R phase.
Refer to PCB LED
Detecting Guide and check
the 3T PCB of R phase.
(7) The
rectifier shunt
down and
HIGH DC LED
lit up.
Voltage limit function failure in the 3B,
which contributes to the DC voltage
becomes over 430V.
Refer to PCB LED
Detecting Guide and check
the 3B PCB.
3C PCB has problem.
Refer to PCB LED
Detecting Guide and check
the 3C PCB.
(8) Abnormal
voltage in
reserve.

If the abnormal cannot be improved as the
aforesaid solution action has been taken.
Refer to PCB LED
Detecting Guide and check
the 3A PCB.
(9) Abnormal
frequency in
reserve.
