circuit in separate conduits.

Parallel Wiring (Single Phase)
• Power cables and signal cables adversely affect each other. Do not wire them in parallel.
• Noise induction may occur if the EtherCAT Slave Terminal is installed in a panel that includes
high-voltage devices. Whenever possible, wire and install them separately.
• Either install the EtherCAT 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.
