Procedure
1) Perform work of item 1 in
!
.
2) Remove screw (ST1TØ4 x 8
lllll
2 pcs.) 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 above the unit, perform work
of 1 in
"
.
Be careful to check the inverter because
high-voltage circuit is incorporated in it.
3) Perform discharging by connecting , polarity
by discharging resistance (approx. 100
Ω
40W) or
plug of soldering iron to , terminals a of the
C14 (printed “CAUTION HIGH VOLTAGE” is at-
tached.) electrolytic capacitor (760µF) on P.C.
board.
Be careful to discharge the capacitor be-
cause 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 between
,
polarity with screwdriver, etc. for discharging.
4) Remove screw (ST1TØ4 x 8
lllll
2 pcs.) fixing the
main body and the inverter box.
5) Remove the front cabinet by performing step 1 in
"
, and remove the fixing screws (ST1TØ4 x 8
l l l l l
)
for securing the main body and inverter box.
6) Remove various lead wires from the holder at
upper part of the inverter box.
7) Pull the inverter box upward.
8) Disconnect connectors of various lead wires.
Requirement :
As each connector has a lock mechanism,
avoid to remove the connector by holding
the lead wire, but by holding the connector.
Remarks
Be sure to remove the connector
by holding the connector, not by
pulling the lead wire.
The connector is
one with lock,
so remove it while
pushing the part
indicated by an
arrow.
