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.
