Wiring CP1L-EL/EM CPU Units
Section 3-4
Noise from External
Wiring
Take the following points into account when externally wiring I/O, power sup-
ply, and power lines.
• When multi-conductor signal cable is being used, avoid combining I/O
wires and other control wires in the same cable.
• If wiring racks are parallel, allow at least 300 mm between them.
• If the I/O wiring and power cables must be placed in the same duct, they
must be shielded from each other using grounded steel sheet metal.
