Wiring Precautions

Power supply wires routed inside the panel must be kept separate from I/O and communication wiring.

Route wiring in separate cable ducting.

If different wires must be placed in the same duct, separate them with an earthed/grounded divider.

Take care when wiring output modules that are designed to work as either source or sink. Incorrect wiring

can cause equipment damage.

Make sure that the operating conditions and environments are within the specification values.

Use proper wire size to meet voltage and current requirements.

Fit cable ends to the cables.

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.
