Precautions for Correct Use
Observe the following precautions to prevent broken wires.
• When you remove the sheath, be careful not to damage the conductor.
• Connect the conductor without twisting the wires.
• Do not weld the conductors. If you do so, vibration may cause the wires to break.
• Do not pull on the cables or bend the cables beyond their natural limit.
Do not place heavy objects on top of the cables or other wiring lines. Doing so may break the
cables.
• Before you insert a wire into a terminal hole, turn the screw that tightens the terminal counter-
clockwise until the terminal is no longer visible. Then, insert the wire so that it is held on the
terminal and screw side of the case and turn the screw clockwise to tighten the terminal.
• Faulty contact will result if you turn the screw counterclockwise to secure the wire. If neces-
sary, remove the wire, make sure it is inserted in the terminal hole, and then connect it again.
