Major Cause ID = 2
1. The battery rack is short-
circuited to the ground.
2. The battery rack is in a
humid environment and the
insulation between the
circuit and ground is poor.
Minor Cause ID = 1, 2
1. The device is installed in a
place with poor ventilation.

Suggestion
Send a shutdown command to
devices connected to the same
DC bus. Start insulation
impedance detection for the
battery rack to locate the fault.
After the fault is located,
perform the following
operations:
1. Check the battery rack-to-
ground impedance. If a
short circuit or inadequate
insulation is found, rectify it.
2. Check that the PE cable of
the device is correctly
connected.
3. If the impedance is lower
than the specified
protection threshold in rainy
and cloudy days, change the
Insulation resistance
protection threshold
setting.
1. Check the ventilation and
ambient temperature of the
device installation position.
2. If the ventilation is poor or
the ambient temperature
exceeds the upper
threshold, improve the
ventilation and heat
dissipation.
3. If the ventilation and
ambient temperature meet
requirements, contact your
dealer or technical support.
