SA/FC Bus and Supply Power
Wiring Guidelines
Comm Bus and Power Supply Terminal Block Rating and
Requirements Table
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.
Important: Refer to the N2 Modernization Guide for
Legacy N2 Controllers (LIT-12012045) for
guidelines when using this device on an N2
bus.
In addition to the guidelines in Comm Bus and Power
Supply Terminal Block Rating and Requirements Table ,
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 FX-PC Series Controllers MS/TP
Communications Bus Technical Bulletin
(LIT-12011670)
or MS/TP Communications Bus for
BCM System Technical Bulletin (LIT-12011908) for
detailed information regarding wire size and cable
length requirements for the SA and FC buses.
