Description

In conjunction with a system configuration that is consistently designed to ensure EMC, line
filters limit the interference emitted by the Power Modules to limit values according to EN
61800-3.
Power Modules blocksize are available in versions with internal line filters (excluding Power
Modules 200 V, FSD-FSF). The limit values of EMC categories C2 and C3 can be complied
with when using these filters.
Power Modules blocksize without an internal line filter require an external line filter in order to
comply with Category C3. Otherwise, it is only permissible to be used with an IT line system,
Category C4.
For Power Modules belonging to the 400 V series, without integrated line filter, external line
filters are available with which Category C1 (cable conducted) can be complied with:
● FSA to FSC: line filter from Siemens AG that can be used as footprint component
● FSD to FSF: You can obtain information about line filters through our "Siemens Product
Partners for Drive Options
drives/de/niederspannungsumrichter/sinamics-zubehoer/Seiten/sinamics-
zubehoer.aspx)".
External line filters are available for Power Modules in the chassis format to comply with limit
values of EMC Categories C2 or C3.
