normal.
2. If the alarm occurs
frequently, check
whether the power grid
voltage is within the
normal range. If not,
contact the local power
operator.
3. If the fault persists for
a long time, check the
connection of the AC
cable.
4. If the AC cable is
correctly connected and
the alarm persists and
affects the operation of
