Precautions for Correct Use
• Use cables with suitable wire sizes for the carrying current. There are also restrictions on the
current due to the ambient temperature. Refer to the manuals for the cables and use the ca-
bles correctly for the operating environment.
• For twisted wires, strip the sheath and twist the conductor portion. Do not unravel or bend the
conductor portion of twisted wires or solid wires.
