work of 1 in ‚.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Be careful to check the inverter because

 

 

 

 

 

 

 

 

 

 

high-voltage circuit is incorporated in it.

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.
