required generates very strong magnetic fi elds in the vicinity of electrolysis tanks and induction furnaces. Workshops manufacturing parts in PVC or rubber use high-frequency welding processes to perform assembly. The propagation of strong magnetic fi elds and high-frequency waves is not easily controllable. It creates local pollution in the midst of which the monitoring and control equipment must be able to operate. | Control Panel Technical Guide How to protect a machine from malfunctions due to electromagnetic disturbance Schneider Electric Contents Introduction p. 4-5 1 Panel design in accordance with EMC rules p. 8-11 Electromagnetic compatibility EMC of the electrical control panel p. 7 Protection of low power signals p. 8 Filtering p. 8 Characteristics of an EMC-compliant panel p. 9 Layout of equipment in a panel p. 10 Reference regulations and standards p. 11 Assembly - panel wiring p. 11-17 Panel assembly p. 13 Installation of enclosures receiving polluted lines p. 13 External routing of cables - entry into the panel p. 14 Cable running in the panel p. 16 Earth connection of shielding p. 17 Earth connection of metal raceways p. 17 Guide for selection of EMC products Enclosures and panels with strengthened EMC Fans and accessories for strengthened EMC Accessories for strengthening EMC p. 18-21 p. 19 p. 20 p. 21
