Classification of EMC performance
Three General classes of EMC performance are available as detailed below:
Class 1: General Industrial
Compliance with European Standard EN 61800-3 (EMC Product Standard for
Power Drive Systems) for use in
Second Environment (Industrial)

Class 2: Filtered Industrial
This level of performance will allow the manufacturer/assembler to self-certify their
apparatus for compliance with the EMC directive for the industrial environment as
regards the EMC performance characteristics of the power drive system.
Performance limits are as specified in the Generic Industrial Emissions and
Immunity standards EN 50081-2 and EN 50082-2.
