Procedure
1) Perform works of items of 1) to 5) of .
2) Take off screw (ST1T Ø4 x 10L, 1 pc.) of
the upper left part of the inverter cover.
• If removing the inverter cover under this
condition, P.C. board can be checked.
• If there is no space in the upper part of
the upper cabinet, perform works of
items 6) to 7) of (1) and remove the
partition fixing plate.
(ST1T Ø4 x 10L, 1 pc.)
CAUTION
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 C10 too 13 (printed as
“CAUTION HIGH VOLTAGE”) electrolytic
capacitor (760µF) of P.C. board.
WARNING
The electrolytic capacitor may not nor-
mally discharge according to error con-
tents and the voltage may remain. There-
fore, be sure to discharge the capacitor.
WARNING
For discharging, never use a screwdriver
and others for short-circuiting between +
and – electrodes. As the electrolytic
capacitor is one with a large capacity, it is
very dangerous because a large electric
spark will occur.
4) Remove various lead wires from the
holder at upper part of the inverter box.
5) Remove the hook for the partition plate
(lower left side).
6) Remove the hook for the side cabinet
(lower left side) and the screw, and lift up
the inverter assembly upward. (ST1T Ø4 x
10L, 1 pc.) In this time, cut off the band
bundling each lead wire.
7) 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.
