range
FAC Failure Grid frequency
is not within
permissible range

a. If the AC voltage is high, then
make sure the AC cable complies
with that required on user manual
and the AC cable is not too long.
b. If the voltage is low, make sure
the AC cable is connected well and
the jacket of the AC cable is not
compressed into the AC terminal.
3. Make sure the grid voltage of your
area is stable and within normal
range.

safety country 3. If FAC failure only appears a
few times and is resolved soon, it
should be caused by occasional grid
frequency unstability.
