Line filter

A separate line filter (see catalog) must be used for the SINAMICS S120 drive line-up. An
additional line filter must be used to suppress interference in other loads. To prevent mutual
interference, this line filter must not be equipped with line-side capacitors with respect to
ground. Filter series B84144A*R120 (EPCOS) is recommended.
In conjunction with line reactors and a systematic plant configuration, line filters limit the
conducted interference emitted by the power modules to the limit values of category C2 to
EN 61800-3. Line filters are only suitable for direct connection to TN systems.
Optional line filter ranges that are coordinated with the power range are available for the
SINAMICS S120 drive system:
● Basic Line Filter for Active Line Modules with line reactor
● Basic Line Filter for Active Line Modules with Active Interface Module
● Wideband Line Filter for Active Line Modules
● Basic Line Filter for Basic Line Modules
● Basic Line Filter for Smart Line Modules
These line filters differ with regard to the frequency range in which they reduce the
conducted emissions.
Note
According to product standard IEC61800-3 RI suppression commensurate with the relevant
operating conditions must be provided and is a legal requirement in the EU (EMC Directive).
Line filters and line reactors are required for this purpose. The use of filters of other makes
can lead to limit value violations, resonances, overvoltages and irreparable damage to
motors or other equipment. The machine manufacturer must provide verification that the
machinery to be operated with the drive products and the installed suppression elements,
e.g. line filters, are CE/EMC-compliant before the machines are approved for delivery.
