This document is an application note that provides a checklist aimed at avoiding electromagnetic compatibility (EMC) issues in various system environments. It outlines specific checkpoints that need to be verified to ensure proper earthing and shielding of components. The checklist includes considerations for common system segments, control cabinets, cable ducts, and the overall system environment. It emphasizes the importance of consistent earthing, the correct layout of cables, and the separation of power and signal lines to minimize interference. Additionally, it details the requirements for grounding connections, the use of braided copper straps, and the significance of maintaining low-impedance connections. The document serves as a practical guide for users to verify that their systems are compliant with EMC standards, thereby enhancing the reliability and performance of their applications.
