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 flat 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-lbs) 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.
