Noise Suppression 4

What are the basic things to keep in mind when dealing with noise?

WEAK POWER (E.G., 24 VDC) AND STRONG POWER (E.G., 100 VAC) FACILITIES ARE

Keep as much distance as possible.

Separate cables without lumping them together.

This is the case.

It may be obvious,

We are sometimes faced with cases where this is not the case,

About the wiring in the control panel,

I will post some links.

Power lines and signal lines are dogs and monkeys

High currents in power lines also generate magnetic fields, which in turn generate noise in signal lines wired in parallel.

Separate the main circuit line (power line) of the inverter from the control line (signal line) of the other device as shown in the figure on the right,
　Even if they cannot be separated, separate them by 30 cm (at least 10 cm) or more if possible.

Never bundle output signal lines with high-voltage lines or power lines, or wire them in close proximity or parallel to each other.
When wiring in close proximity, use a duct. If they are in close proximity, separate them with a duct or wire them in separate conduits. At this time, be sure to ground the ducts and conduits.
and conduit must be grounded.
