Table 1 provides information about terminal block functions, ratings, and requirements.

Table 1 also provides wire size, cable type, and cable length guidelines for wiring the CH-PCV communication buses and supply power.

In addition to the guidelines in Table 1, observe these guidelines when wiring the SA Buses and supply power:

  • Run all low-voltage wiring and cables separate from high-voltage wiring.

  • All SA Bus cables, regardless of wire size, should be twisted, insulated, stranded copper wire.

  • Shielded cable is strongly recommended for all SA Bus cables.

  • Refer to the MS/TP Communications Bus for the BCPro™ System Technical Bulletin 912011908) for detailed information regarding wire size and cable length requirements for SA Buses.
