3-3-4 Noise Prevention Wiring
• To prevent inductive noise, do not wire the communications line, PLC power lines, and other power
lines near to each other. Keep the power lines for Inverters, motors, regulators, and contactors, the
communications lines, and the PLC power lines separated from each other by at least 300 mm.
Also, provide separate conduits or ducts for the communications lines and power lines.
• Do not install communications lines and PLC power lines onto the control panel on which high-volt-
age devices are mounted.
• Because noise currents flow through metallic equipment (such as casings), the communications
cables should be placed as far away from metallic equipment as possible.
