4.3 Grounding and Shielding
In most cases controllers are installed in enclosures along with other devices, which
generate electromagnetic radiation (for example, relays, contactors, transformers, motor
invertors, etc.). Such electromagnetic radiation can induce electrical noise into both
power and signal lines, as well as direct radiation into the controller, causing negative
effects on the system. For this reason, an appropriate grounding, shielding, and other
protective steps should be taken at the installation stage to prevent negative
electromagnetic radiation effects, for example:
control cabinet grounding;
