NX-series EtherNet/IP Coupler Unit User’s Manual (W536)
• To avoid overheating the conduits when using conduits for wiring, do not place wires for a single
circuit in separate conduits.
• Power cables and signal cables adversely affect each other. Do not wire them in parallel.
• Noise induction may occur if the EtherNet/IP Slave Terminal is installed in a panel that includes
high-voltage devices. Whenever possible, wire and install them separately.
• Either install the EtherNet/IP Slave Terminal a minimum of 200 mm away from high-voltage lines
or power lines, or place the high-voltage lines or power lines in metal tubing and completely
ground the metal tubing to 100 Ω or less.
