Be careful to check the inverter because
high-voltage circuit is incorporated in it.
Be careful to discharge the capacitor
because the electrolytic capacitor cannot
naturally discharge and voltage remains
according to trouble type in some cases.
NOTE :
This capacitor is one with mass capacity.
Therefore, it is dangerous that a large
spark generates if short-circuiting be-
