4. Don't shor t between the LIVE side ground and ISOLATED

(NE UTRAL) side ground or EARTH side ground when
repairing.

Some model's power circuit is partly different in the GND. The
diff er enc e of th e GND is s ho wn b y th e LIV E : ( ") side GN D, the
ISO LATE D(N EUTRAL) : (#) si de GND and EARTH : ( $) side
