Line filters
In conjunction with line reactors and a consequential EMC-compliant system design, line filters
limit the conducted electromagnetic emissions generated by the Line Modules to the limit
values according to IEC 61800-3.

Overview of line filters
The following line filter versions can be used for operating the Smart Line Module.

Basic Line Filter for S220 Smart Line Modules
16 kW
24 kW
Basic Line Filters are used to attenuate conducted interference in accordance with the
specifications contained in the EMC legislation. They are mainly effective in the frequency range
from 9 kHz to 30 MHz; this is the range relevant to ensure compliance with the appropriate
standard.
They can be used for Smart Line Modules in conjunction with the associated line reactors.
They are only suitable for direct connection to line supplies with grounded neutral point (TN or
TT). An isolating transformer is required for other power systems.
Data regarding the radio interference voltage categories and maximum total cable lengths that
can be achieved is provided in Chapter Combination options of Line Modules with line reactors
and line filters (Page 114). The sum of the lengths of all motor cables, line supply cable from the
line filter to the Line Module is called the total cable length.

Safety instructions for line filters
Electric shock due to residual charges in power components
As a result of the capacitors, a hazardous voltage is present for up to 5 minutes after the power
supply has been switched off.
Contact with live parts can result in death or serious injury.
• Wait for 5 minutes before you check that the unit really is in a no-voltage condition and start
