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.
• Different wire groups should cross at 90° inside an enclosure.
• Minimum spacing between different wire groups in the same tray should
be 16 cm (6 in.).
• 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 8 cm (3 in.).
• For additional guidelines, please refer to Wiring and Ground guidelines,
publication DRIVES-IN001A-EN-P.
• Wire earth ground to control terminal 14.
• Use shielded wire for: PTC Input
Tach Input
Ground Fault Input
