Wire Layout for the Power Supply System
Observe the following points when wiring the power supply system.
• Separate the Controller power supply from the I/O device power supply and install a noise filter near
the Controller power supply feed section.
• Use an isolating transformer to significantly reduce noise between the Controller and the ground. In-
stall the isolating transformer between the Controller power supply and the noise filter, and do not
ground the secondary coil of the transformer.
• Keep the wiring between the transformer and the Controller as short as possible, twist the wires
well, and keep the wiring separate from high-voltage and power lines.

Wiring External I/O Signal Lines
Observe the following points when wiring external I/O signal lines.
• To absorb reverse electromotive force when an inductive load is connected to an output signal, con-
nect a surge suppressor near the inductive load in an AC circuit, or connect a diode near the induc-
tive load in a DC circuit.
