2-4-4 Noise Prevention Wiring

To prevent inductive noise, do not wire the communications line, SYSMAC 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 SYSMAC 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 SYSMAC power lines onto the control panel on which high- voltage 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.

•Ground the shielding wire on the communications cable at one point.

•If the same ground is used for the communications cables and communications power supply, there is a possibility that noise may be transmitted through the ground line to the communications line. In order to avoid this, be sure that the power line ground and the grounds for the communications cables and the communications power supply are located as far from each other as possible.
