8 Alarm Reference
Suggestion
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
not, contact the local power
operator. If yes, modify the
power grid undervoltage
protection threshold after
obtaining the consent of the
local power operator.
3. If the fault persists for a
long time, check the
connection between the AC
switch and the power cable.

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.
