Wiring
Wire in an industrial control application can be divided into three
groups: power, control, and signal. The following recommendations
for physical separation between these groups is provided to reduce the
coupling effect.
• Minimum spacing between different wire groups in the same tray
should be 6 in. (16 cm).
• Wire runs outside an enclosure should be run in conduit or have
shielding/armor with equivalent attenuation.
• Different wire groups should be run in separate conduits.
• Minimum spacing between conduits containing different wire
groups should be 3 in. (8 cm).
