Procedure on tightening harness (snubber capacitor) and power transistor with screw.

A metallic connection binder is set in each hole of the inverter PCB of "P", "N", "U", "V", and "W"
beforehand. Then tighten the harness (snubber capacitor) and the power transistor with the screw together.

(Connect snubber capacitor with "P" and "N".)
