The radiated interference is usuallygrounded by the metallic enclosure of the drive as well as through the use of shielded cable, anddoes not cause any problems in the environment. The galvanically coupled interference may have tobe filtered in order to achieve EMC compliance. The Vacon NX range of AC drives contain an internalfilter for bringing the drives into compliance with the standard (specifically IEC 61800-3:2004). Insome cases, an additional filtering is required. Both input and output filters are available for theVacon NX range of drives. The drive may also have to be protected against various overvoltagesoccurring in the supply. On the input side RFI filters and additional chokes can be installed, on theoutput side dU/dt filters or sine filters.1.4 Type designation codeFigure 1.
