Communications bus and supply power terminal blocks, ratings, and requirements provides information about the functions, ratings, and requirements for the communication bus and supply power terminals; and guidelines for wire sizes, cable types, and cable lengths when wiring the communication buses and 24 VAC supply power.

In addition, observe these guidelines when wiring an SA or FC bus and supply power:

  • Run all low-voltage wiring and cables separate from high-voltage wiring.
  • All SA and FC bus cables, regardless of wire size, should be twisted, insulated, stranded copper wire.
  • Shielded cable is strongly required for all SA and FC bus cables.
