Procedure
1. Detachment
1) Perform work of items 1. of
and
.
2) Remove screw (ST1TØ4 x 10
lllll
1 pc.) of the
upper part of the front cabinet.
• If removing the inverter cover in this condition,
P.C. board can be checked.
• If there is no space in the upper part of the
upper cabinet, perform work of
.
Be careful to check the inverter because
high-voltage circuit is incorporated in it.
3) Perform discharging by conn , – polarity
by discharging resistance (approx. 100
Ω
40W) or
plug of soldering iron to + , – terminals of the
C15 (printed “CAUTION HIGH VOLTAGE” is
attached.) electrolytic capacitor (500µF) on P.C.
board.
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-
tween + , – polarity with screwdriver, etc.
for discharging.
4) Remove screw (ST1TØ4 x 10
lllll
1 pc.) fixing the
main body and the inverter box.
5) Remove various lead wires from the holder at
upper part of the inverter box and wiring holder
at right side of the terminal block.
6) Remove the lead wire from the bundled part at
left side of the terminal block.
7) Pull the inverter box upward.
8) Disconnect connectors of various lead wires.
