2) Remove screw (ST1TØ4 x 10l 1 pc.) 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 in the upper part of the

3)Perform discharging by connecting + , – polarity by discharging resistance (approx. 10040W) or

plug of soldering iron to + , – terminals of the C14 (printed “CAUTION HIGH VOLTAGE” is attached.) electrolytic capacitor (500µF) on P.C. board.

Be careful to discharge the capacitor

 

because the electrolytic capacitor cannot

 

naturally discharge and voltage remains

4)Remove screw (ST1TØ4 x 10l 1 pc.) 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.

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.
