Suitable wiring
Precautions
Do not tighten terminal screws with torque beyond the specified range. Otherwise it may cause equipment failure or
malfunction.
Wire end treatment
Treat stranded and solid wires as they are or use wire ferrules with insulation sleeves for wiring terminals.
■When stranded and solid wires are treated as they are
• Twist the end of stranded wires and make sure that there are no loose wires.
• Do not solder-plate the electric wire ends.
■When wire ferrules with insulation sleeves are used
Depending on the thickness of a wiring sheath used, it may be difficult to insert the sheath into an insulation sleeve. Refer to
the external dimensions as a reference to select wires.
