Electromagnetic compatibility
Definition
Electromagnetic compatibility refers to the capability of electrical equipment of reliably
performing its dedicated function in an electromagnetic environment, without causing
interference in the same environment.
The ET 200pro distributed I/O system meets all requirements of EMC legislation for the
European market. This requires that the ET 200pro distributed I/O system complies with the
requirements and guidelines for electrical installation.
