26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Proper grounding and shielding aren't just best practices; they are the foundation of a reliable and safe system. Neglecting them leads to phantom faults, system crashes, and costly downtime. This guide will visually demonstrate why. This publication gives you general guidelines for installing an Allen-Bradley industrial automation system that may include programmable controllers, industrial computers, operator-interface terminals, display devices, and communication networks. Done right, it provides a low-impedance fault path for safety and a clean reference for analog signals. Done wrong, it creates ground loops that corrupt analog readings, induce noise on sensitive signals, or worse β fails. This manual is intended for users of Schneider Electric PLC systems during configuration and installation and provides information regarding grounding and measures for electromagnetic compatibility (EMC). Each DISTRIBUTION BOX and controller must be grounded.
