4) Remove screw (ST1TØ4 x 10 2 pcs.) 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.
Procedure

cabinet, perform work of
Be careful to check the inverter because
high-voltage circuit is incorporated in it.
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 + , –
polarity with screwdriver, etc. for discharging.
Requirement :
As each connector has a lock mechanism,
avoid to remove the connector by holding
the lead wire, but by holding the connector.
