age
Major Cause ID = 1
The grid voltage exceeds
the upper threshold or the
overvoltage duration
exceeds the time that
triggers high voltage ride-
through (HVRT).
1. If the alarm occurs occasionally,
the power grid may be abnormal
temporarily. The device
automatically recovers after
detecting that the power grid
becomes normal.
2. If the alarm occurs frequently,
check whether the power grid
voltage is within the allowed
range. If no, contact the local
power operator. If yes, modify the
power grid overvoltage protection
threshold after obtaining the
consent of the local power
operator.
3. Check whether the peak voltage of
the power grid is too high. If the
fault occurs frequently and persists
for a long time, contact the local
power operator.

ce
Major Cause ID = 1
The dierence between
grid phase voltages exceeds
the upper threshold.
1. If the alarm occurs occasionally,
the power grid may be abnormal
temporarily. The device
automatically recovers after
detecting that the power grid
becomes normal.
2. If the alarm occurs frequently,
check whether the power grid
voltage is within the normal range.
If no, contact the local power
operator.
3. If the fault persists for a long time,
check the connection of the AC
cables.
4. If the AC cables are correctly
connected and the alarm persists
and
aects the operation of the
plant, contact the local power
operator.
