3.7 Line filter
3.7.1

Description

In conjunction with a suitably EMC-compliant system configuration, line filters limit the
conducted interference emitted by the Power Modules to limit values according to EN 61800-
3.
A line filter according to the catalog must be used for the SINAMICS S120 drive line-up.

Classification of EMC behavior

The EMC environments and the EMC categories are defined in the EMC product standard
EN 61800-3 as follows:
Environments
First environment (public systems)
An environment that includes domestic premises and establishments that are connected
directly to a public low-voltage line supply without the use of an intermediate transformer.
Examples: Houses, apartments, commercial premises, or offices in residential buildings.
Second environment (industrial systems)
An environment that includes all other establishments that are not connected directly to a
public low-voltage line supply.
Examples: Industrial areas and technical areas of buildings that are supplied by an assigned
transformer.
Categories
Category C1
Drive systems with a rated voltage < 1000 V, which are intended for use in the first
environment.
Drive systems which correspond to category C1 can be installed in the first environment
without restrictions.
Category C2
Drive systems with a rated voltage < 1000 V, which are neither plug-in devices nor moveable
devices and which, when used in the first environment, are intended only to be installed and
commissioned by an expert.
Drive systems which correspond to category C2 may only be used in the first environment if
they are installed by an expert, with limit values for electromagnetic compatibility observed.
