Table 1 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 controller's communication buses and supply power.

In addition to the guidelines in Table 1 observe these guidelines when wiring an SA or FC bus and the 24 VAC 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 recommended for all SA and FC bus cables.
  • Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for detailed information regarding wire size and cable length requirements for the SA and FC buses.
  • Refer to the N2 Communications Bus Technical Bulletin (LIT-636018) for detailed information regarding wire size and cable length requirements for the N2 bus.
