Ensure that the wiring is not pinched when fitting the terminal box cover. Pinching the wiring may cut it.
Install wiring so that it is not tight and under tension. Wiring under tension may break, or overheat and burn.
Fix power source external input/output line wiring to control box by using buffer bushing for tensile force to prevent electric
shock. (PG connection or the like.) Connect transmission wiring to transmission terminal block through the knockout hole
of control box using ordinary bushing.
After wiring is complete, make sure again that there is no slack on the connections, and attach the cover onto the control
