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.
