Page 13: Rs485 Grounding And Shielding
Hardware User Manual 4.4.2 RS485 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. -
