EMC
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.
