19.5 Measures for Wiring in Panel

Cables act as antennas to propagate unnecessary noise, and thus must be appropriately shielded and treated.
The following measures must be sufficiently considered for the cables that carry out high-speed communication.

19.5.1 Precautions for Wiring in Panel

(1) If the cables are led unnecessary in the panel, they will pick up noise. Pay attention to the device layout and wire
length so that the wiring length is as short as possible.
