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. Check whether battery
polarities are correctly
installed by using a
multimeter. If no, correct the
installation.
2. Check whether the battery
input voltage of the UPS is
normal. If yes, the battery
sampling circuit of the power
module is faulty. Replace the
power module.
If the BCB box is configured,
check whether the BCB box trips.
If it trips, close the BCB box
switch.
1. Check that battery cables are
correctly connected.
2. Check that the battery terminal
voltage is normal.
3. Check that the battery fuse in
the power module is intact.
1. Check whether battery
parameters are correctly set.
2. If they are correctly set, certain
batteries may be faulty.
3. Check whether the battery
neutral wire is correctly
connected.
