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.
