Precautions when wiring

For crimp terminal connection

When using crimp terminals, please be sure to attach an insulated coating.

In case of direct cable connection

Please insert it until the cable coating touches the terminal fitting.
The stripping length of the cable coating should be more than the width of the washer.
When connecting 2 cables directly, please use the same size for both cables.

*Please see the manufacturer's catalog for product information other than the above.
