Guidelines for electromagnetic compatibility (EMC)
4.5.1
Overview
These EMC Guidelines answer the following questions:
● Why are EMC guidelines necessary?
● What types of external interference have an impact on the system?
● How can interference be prevented?
● How can interference be eliminated?
● Which standards relate to EMC?
● Examples of interference-free plant design
