Chapter 1 Drive Comparisons
EMC Filters
PowerFlex DC drives require the use of an external EMC filter in order to comply
with the EMC directive (2004/109/EC) and emission limits of EN 61800-3:
2004. PowerFlex DC drives have been tested and verified for compliance to the
emission limits of EN 61800-3: 2004 using only the specific input filters and
motor cable lengths indicated in this table:
A list of recommended alternate filters can be used in place of the Rasmi and
EPCOS filters listed in the table above. See Alternate EMC Filters in Appendix
A of the PowerFlex Digital DC Drive User Manual, publication 20P-UM001
.
