Solution
Verify the cable connections.
1. Secure or connect the neutral
wire to the cabinet if it is loose
or disconnected.
2. Check that the neutral wire to
the power distribution system
is normal.
Check whether the mains voltage
ranges from 80 V (excluding 80
V) to 176 V. If no, the mains
monitoring circuit for the power
module is faulty. Replace the
faulty module.
1. Check the bypass input voltage
or cable connections with a
multimeter.
2. Check the voltage system and
bypass voltage thresholds
configured on the LCD.
1. Check the bypass input voltage
or cable connections with a
multimeter.
2. Check the bypass input
frequency. Check the rated
frequency and frequency range
configured on the LCD.
Check whether the cable phase
sequence is correct using a
multimeter. If no multimeter is
available, exchange the positions
of any two cables.
1. Secure or connect the neutral
wire to the cabinet if it is loose
or disconnected.
2. Check that the neutral wire to
the power distribution system
is normal.
1. Check whether battery
polarities are correctly
installed by using a
multimeter. If no, correct the
installation.
2. Check whether the battery
