Wiring Safety and Noise Controls
I/O Signal Wiring
Whenever possible, place I/O signal lines and power lines in separate ducts or
conduits both inside and outside of the control panel.
If the I/O wiring and power wiring must be routed in the same duct, use
shielded cables and connect the shields to the GR terminal to reduce noise.
Inductive Loads
When an inductive load is connected to an I/O Unit, connect a surge suppres-
sor or diode in parallel with the load as shown below.
Note
Use surge suppressors and diodes with the following specifications.
