Wiring Precautions
To help prevent noise and interference problems, separate all control, communication and power lines by
placing them in a separate ducts.
If different wires must be placed in the same duct, separate them with an earthed/grounded divider.
• If the lines cannot be separated, use shielded lines and create a ground from the shield
line.
• Use noise-reducing external wiring methods to increase overall system reliability.
• To prevent power surges or noise interference, use ducts to separate all DC I/O
or current circuit wires from communication cables.
• To prevent malfunctions due to noise, communication cables must be wired
separately from high-frequency lines and power lines such as high-voltage lines,
high-current lines, and inverters.
