9.3 Wiring inside and outside the panel

Wiring inside

Run power lines, servo amplifier drive wires, and communication cables so that they do not cross each other.

Noise interference that is generated by cables that cross each other may cause malfunctions.

Surge suppressors are an effective way to filter out surge noise that is generated from no fuse breakers (NFB),

electromagnetic contactors (MC), relays (RA), solenoid valves, and induction motors.

Refer to the section to follow for surge killers.

Uncrossed power lines and

communication cables

Outside the panel

To pull the power line and communication cable out of the panel, make two pullout holes away from each other and pull

the cables through.

Putting both cables through the same pullout hole will increase noise interference.

Keep the power line and communication cable inside the duct at least 100 mm away from each other.

If that is not possible, the use of a metal separator inside the duct can reduce noise interference.
