Notes :
(*) In case of this error message, it is possible that the supply does not work due to a
snubber problem on the power distribution board (EY-80203). 3 possibilities:
Æ
Snubber resistor cut with cap=100nF (Malfunction is not caused by the snubber)
Æ
Resistor not cut, capacitor = 4,7nF (disc shape) (Malfunction is not caused by
the snubber)
Æ
Resistor not cut, capacitor = 100nF (rectangular shape), malfunction may be
caused by snubber, so cut resistor.
