How to reduce EMC risks in EPS field wiring?

The wiring process during EPS installation directly affects its final EMC performance; poor workmanship can render a good design ineffective. Key points to reduce potential hazards:

1. Grounding connection specifications: Grounding wires should be short and thick, and paint or oxide layers should be removed from connection points. Appropriate terminals should be used and securely tightened to ensure low-impedance connections.

2. Cable shielding treatment: The shielding layer of shielded cables must use appropriate connectors or clamps to achieve 360-degree overlapping grounding; "pigtail" connections are strictly prohibited.

3. Cable classification and laying: Cables should be strictly classified as power, signal, and communication cables, and run in separate cable trays or maintain sufficient spacing to avoid parallel laying.

4. Filter installation specifications: Input and output lines should be bundled separately on both sides of the filter to prevent noise from directly coupling to the filtered side.

5. Connector installation: Shielded connectors must have good conductive contact with the cabinet panel. Clear installation drawings and process requirements must be provided, and installers must be trained to ensure that on-site construction conforms to the EMC design intent.
