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.
