1560D-UM051D-EN-P – February 2005
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 six inches (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 three inches (8 cm).
Accessory Requirements
When connection of the Bulletin 825 converter module or Bulletin 1202
communication cable is required, a ferrite core suppressor (Fair-Rite PN
2643802702 or equal) should be used in conjunction. Mount the suppressor
as close to the controller as practical, wrapping the cable twice through the
suppressor.
