1. Check whether cables to mains are
disconnected, loose, or incorrectly
connected.

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 unit is not normal.
Replace the faulty unit.
