You can find the EMC Directive on the Internet:
60612658)
An appropriately trained specialist must carry out the installation, who has the necessary
experience to install and/or commission variable-speed power drives, including the associated
EMC issues.
Second environment - category C4
An unfiltered converter corresponds to category C4.
EMC measures in the "second environment", category C4, are implemented on the basis of an
EMC plan at the system level.
Second environment - category C3
Immunity
The inverters comply with the requirements of the standard.
Interference emission for unfiltered inverters
Inverters with integrated filter comply with the requirements of the standard.
Cable-conducted, high-frequency noise emission of an unfiltered inverter
Either install an external filter for the inverter - or install corresponding filters at the system level.
