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.
The Power Modules in the blocksize format are available in versions with internal line filters.
The limit values of EMC categories C2 and C3 can be complied with when using these
filters.
Power Modules in the blocksize format without internal line filter correspond as standard with
Category C3 - or when used on IT line supplies, Category C4.
For Power Modules belonging to the 400 V series, without integrated line filter, external line
filters can be used in order to achieve Category C1 (cable conducted):
● FSA to FSC: line filters from Siemens that can be base mounted
● 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.
