10 Alarm Reference
Suggestion
1. Check whether the AC
voltage is normal.
2. The AC power cable is
disconnected or the AC
circuit breaker is OFF.
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
input power cable.
