Line filters

3.6.1

Description

Line filters have the task to attenuate conducted interference emission in the frequency
range according to the specifications of EMC legislation. They are mainly effective in the
frequency range from 150 kHz to 30 MHz; this is the range relevant to ensure compliance
with the appropriate standard.
In conjunction with a line filter and the associated line reactor, drive line-ups with S120
Combi 10 kW, 16 kW and 20 kW Power Modules and a maximum total cable length up to
175 m, fulfill Category C2 according to EN 61800-3. An EMC compliant design is always
assumed.
Note
The line filter is only suitable for direct connection to TN line supplies. An isolating
transformer with vector group "Dyn" and grounded neutral point must be used when
connecting to other line supplies. The line filter and the control cabinet must be connected to
the isolating transformer neutral point through a low inductance connection.
