Siemens SINAMICS DCM Operating Instructions Manual page 528

Appendix A
A.1 Certifications and standards
Korean Certification (KC)
The EMC limit values to be complied with for Korea correspond to the limit values of the
EMC product standard for variable-speed electric drives EN 61800-3, category C2 or limit
value class A1 according to EN55011.
With suitable additional measures, the limit values according to category C2 or according to
limit value class A1 are maintained.
To do this, an additional radio interference suppression filter (EMC filter) must be used and
the converters must be installed in the control cabinet in compliance with EMC rules.
The appropriate radio interference suppression filters (for the field and armature circuits) for
the SINAMICS DC MASTER are listed in Catalog D23.1.
Additional notes are provided there as well as technical data and constraints regarding the
use of radio interference suppression filters, such as:
● The use in grounded line supplies
● And the mandatory use of a commutating reactor
Detailed information about the basics of EMC and EMC-compliant design of drives can be
found in the Chapter "Connecting up".
