Part name
Inverter
assembly
Procedure
Remarks
1)
Perform work of item 1 in
.
2)
Remove screw (ST
2
TØ4 × 10L 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 C10 (printed “
WARNING
HIGH VOLTAGE” is attached.) electrolytic
capacitor (
50
0µF) 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
between
,
Requirement
As each connector has a lock mecha-
nism, avoid to remove the connector by
holding the lead wire, but by holding the
connector.
Be sure to remove the connector by
holding the connector, not by pulling
the lead wire.
4)
Remove screw (ST
2
T
∅
4 x 10L 4pcs.) fixing
the terminal part of inverter box to the
side
cabinet (right).
5)
Remove the front cabinet by performing step
1 in
k
, and remove the fixing screws
(ST
2
T
∅
4 x 10L) for securing the
partition
plate
and inverter box.
6) Remove the fixing screw (ST2TØ4 × 10L 1
pcs.) securing the wiring cover and inverter
box.
7) Remove the fixing screw (ST2TØ4 × 10L 2
pcs.) for securing the motor base and
inverter box.
8) Remove various lead wires from the holder
at upper part of the inverter box.
9) Pull the inverter box upward.
10) Disconnect connectors of various lead wires.
(Refer to next page for detail of leads and
connector)
•
After removing screw, remove the wiring
cover pulling it downward.
