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.

7) Disconnect connectors of various lead

 

 

 

wires.

 

 

Remove the connectors

As each connector has a lock mechanism,

 

 

 

avoid to remove the connector by holding

 

 

 

the lead wire, but by holding the connector.
