NX-series PROFINET Coupler Unit User’s Manual (W623)
Observe the following points.
• The coils and contacts in electromagnetic contactors and relays in an external circuit are sources of
noise. Do not install them close to the Profinet IO Device Terminal. Locate them at least 100 mm
away from the Profinet IO Device Terminal.
Observe the following points when wiring the power supply system.
• Separate the Profinet IO Device Terminal power supply from the IO device power supply and install a
noise filter near the power supply feed section.
• Use an isolating transformer to significantly reduce noise between the Profinet IO Device Terminal
and the ground. Install the isolating transformer between a power supply and the noise filter, and do
not ground the secondary coil of the transformer.
