Solution
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 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.
