NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)
When you use any ferrules other than those in the above table, crimp them to the twisted wires so
that the following processed dimensions are achieved.
Using Twisted or Solid Wires
If you use twisted wires or solid wires, use the following table to determine the correct wire specifica-
tions.
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
cables 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.
If more than 2 A will flow on the wires, use plated wires or use ferrules.
