HF Filter
It is recommended to install one HF filter (Catalog No. 20S-RFC) in every
system. When this filter is used, the HF emission limits for class A, group
2* (EN 55011) in the 2nd environment (industrial supply network)
according to the product standard EN 61800-3 are met and the Bus Supply
fulfills CE conformity.
The HF filter is connected in front of the AC line reactor between the three
AC line input phases and the protection earth conductor PE (
Figure A.5 ).
