• Keep the wiring between the transformer and the Profinet IO Device Terminal as short as possible,
twist the wires well, and keep the wiring separate from high-voltage and power lines.
Supplying IO Power from the NX Bus
Supplying IO Power from External Sources
Observe the following points when wiring external IO 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.
