Alarm Name Severity Possible Cause Suggestion
2062 Low Insulation
Resistance
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 battery rack and
ground is poor.
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 resistance
between the battery
rack and the ground. If
a short circuit or
insucient insulation is
found, rectify it.
2. Check the battery rack-
to-ground impedance.
If a short circuit or
inadequate insulation is
found, rectify it.
3. If the impedance is
lower than the
specied protection
threshold in rainy and
cloudy days, change
the Insulation
resistance protection
threshold setting.

Cabinet
Overtemperature
Minor Cause ID = 1, 2
1. The device is installed in
a place with poor
ventilation.
2. The ambient
temperature is high.
3. The device is faulty.
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.
