The shield is connected using a clamp or an EMC-safe cable gland (PG-gland) or other method that can ensure an efficient high frequency connection. The shield connection should cover as wide an area and have as low a resistance as possible. Never connect the shield to ground. Fig. 4: Optimal grounding with star-shaped structure The quality of a shield connection is reflected in. Protective Earthing is a requirement to divert unwanted, potentially hazardous currents from all exposed metallic parts such as equipment chassis, racks, cabi-nets, cable trays, conduit, and patch panels for personnel safety reasons and to avoid potential damage to equipment. However, the idea is always the same - electrical devices are not allowed to interfere with each other. The purpose of this presentation is to introduce some practical methods. 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.
