The following table provides information about the functions, ratings, and requirements for the communication bus and supply power terminals. The table also provides guidelines for wire sizes, cable types, and cable lengths for when you wire the controller's communication buses and supply power.

In addition, observe these guidelines when you wire an FC bus and the 24 VAC supply power:

  • Run all low-voltage wiring and cables separate from high-voltage wiring.
  • All SA bus cables, regardless of wire size, must be twisted, insulated, stranded copper wire.
  • Shielded cable is strongly recommended for all SA bus cables.
  • Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for detailed information regarding wire size and cable length requirements for SA buses.
