DISCHARGING OF THE CHARGING CAP
ACIT
OR (C901)
The char
ging capacitor is char
ged up to the maximum 330
V
potential. There is a danger of electric shock by this high voltage when the capacitor is handled by hand.
The electric shock is caused by the
char
ged voltage which is kept without dischar
ging when the main
power of the unit is simply turned of
f.
Therefore, the remaining
voltage must be dischar
ged as described below
.
