Wiring For the wiring, strip off the sheath of a cable, and use it with a crimp terminal. For a single wire, strip off the sheath of the wire and apply directly. Insert the crimp terminal or the single wire into a socket of the terminal. Strip the signal wires as follows. - Page 34 Crimp the terminals on the wire. Insert the wire into a crimp terminal, making sure that 0 to 0.5 mm of the wire protrudes from the end of the sleeve. Check the condition of the crimp terminals after crimping. Do not use the crimp terminals of which the crimping is inappropriate, or the face is damaged.
