Understanding Your SLC 500/1746 Control System B-9
•
Segregate I/O wiring by signal type. Bundle wiring with similar electrical
characteristics together.
Wires with different signal characteristics should be routed into the enclosure
by separate paths. Refer to Allen-Bradley Programmable Controller Grounding
and Wiring Guidelines, publication number 1770-4.1.
Grounding Guidelines
In solid-state control systems, grounding helps limit the effects of electrical
noise due to electromagnetic interference (EMI). The ground path for the
adapter and its enclosure is provided by the equipment grounding conductor.
ATTENTION
!!!!
Handle the TTL module by its ends, not metallic surfaces.
Electrostatic discharges can damage the module. Do not
expose the TTL module to electrostatic charges.
ATTENTION
!!!!
United States Only: If the adapter is being installed within
a potentially hazardous environment (i.e., Class I, Division
2), all wiring must comply with the requirements stated in
the National Electrical Code 501-4 (b).
