Wiring Guidelines
Follow the guidelines below when planning your system wiring.
• To limit noise, keep signal wires as far away as possible from power and load lines.
• To ensure proper operation and high immunity to electrical noise, always use
Belden™ 8761 (shielded, twisted pair) or equivalent wire.
• Connect the shield drain wire to the earth ground of the chassis.
• Tighten terminal screws using a standard or cross-head screwdriver. Each screw
should be turned tight enough to immobilize the wire’s end. Excessive tightening
can strip the terminal screw. The torque applied to each screw should not exceed
0.7 to 0.9 Nm (6 to 8 in-lb) for each terminal.
• Follow system grounding and wiring guidelines found in your SLC 500 Modular
Hardware Style Installation and Operation Manual, publication 1747-6.2.

ATTENTION
To prevent shock hazard, care should be taken when wiring the
module to analog signal sources. Before wiring any analog module,
disconnect power from the SLC 500 system and from any other
source to the analog module.
