 Grounding Methods
If the DIN Track is made of steel and the surface is not treated to produce an insulating material, you
can omit grounding the functional ground terminal on any Unit that has one, as shown in the follow-
ing figures.
• DIN Track Made of Steel and Surface Not Insulated
 Precautions when Grounding
• To prevent influence from leakage current from other electrical devices, electrically isolate the
panel in which the EtherNet/IP Slave Terminal is housed from other devices.
• If high-frequency equipment is present, then ground not only the high-frequency equipment but
also the panel itself in which the EtherNet/IP Slave Terminal is housed.
• To ground the shield wire when using shielded cables for I/O wiring, wire the ground according the
shield treatment specifications for the NX Unit that is used.
Wire communications cables according to the shield treatment specifications for the Unit.
