A.2.4.2 ET 200pro FC frequency converter in general industrial application
Explanatory notes for general industrial application
In this EMC application, the manufacturer/assembler must certify the devices used as
compliant with the EMC directive for industrial environments. The limit values are in line with
the generic standards EN 61000-6-4 for generic emissions (noise radiation) and EN 61000-
6-2 interference immunity in the second environment (industrial).
Limit values for general industrial application
The following tables contain the key limit values for compliance with the generic standards.

The requirements of the generic standards in respect of interference immunity are met. The
required values for interference emission are complied with if installation takes place
according to EMC installation guidelines.
