2. If cable connections are
correct, measure the mains
voltage with a multimeter. If
the mains voltage exceeds 280
V, the mains input is not
normal; if the mains voltage is
less than 272 V, the sampling
circuit of the power module is
not normal. Replace the faulty
module.

correct, measure the mains
voltage with a multimeter. If
the mains voltage is less than
80 V, the mains voltage is not
normal; if the mains voltage
exceeds 88 V, the power
module sampling circuit or
fuse may not be working
properly. Replace the faulty
module.
