Inverter
assembly
Procedure
1. Detachment
1) Perform work from item 1) to 5) of
.
2) Remove screw (ST1T Ø4 x 10
1 pc.) of the upper
left part of the inverter cover.
• 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 from 6) to 7) of
and
remove the partition fixing plate
(ST1T Ø4 x 10
1 pc.).
Be careful to check the inverter because
high-voltage circuit is incorporated in it.
3) Perform discharging by connecting the discharging
resistance (approx. 100Ω 40W) or plug of soldering
iron to
, terminals of the C15 (printed “CAU-
TION HIGH VOLTAGE” is attached.) 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 (Ø4 x 10
2 pcs.) fixing the valve
clamping plate/the inverter box, and fixing the back
panel/the inverter box.
5) Remove various lead wires from the holder at
upper part of the inverter box and cut 2 tie-lap ties
binding each lead wires :
6) Pull the inverter box upward.
7) Disconnect connectors of various lead wires.
