4.6 Line Filters
Line Filters consist of combinations of capacitors, reactors, resistors and voltage
limiters that are intended to reduce the electromagnetic influence of the environment.
4.6.1 Line Filters and CE Compliance
The direction of influence is bi-directional, i.e. there is a reaction in the units of
emission of conducted disturbances, and, at the same time, an improvement in the
immunity of the drive to interference that occurs in the case of lightning strikes, tripped
fuses, or simple switching activities.

The filter should be mounted to a grounded conductive surface.
