Armature Filters
If the end-user is not using a CE-approved motor, a filter on the armature
must also be used. See Table 5 for recommended armature filters. Use
model CE04RG with drives rated for 3 ADC or below, and model CE10RG
with drives rated for 10 ADC or below.

Wire the armature filter to the DC output of the drive, as close to
the drive as possible. The ground connection from the filter must
be wired to solid earth ground (resistance less than 500 ohms);
not machine ground. This is very important!
The end user must use the filtration listed in this addendum to comply with
CE. The OEM may choose to provide alternative filtering that encompasses
the Minarik drive and other electronics within the same panel.The OEM
has this liberty because CE is a machinery directive.
Whether or not every component in the OEM’s machinery meets CE, the
OEM must still submit his machine for CE approval. Thus, no component
must necessarily meet CE within the machine, as long as the OEM takes
the necessary steps to guarantee the machine does meet CE. By the same
token, even if every component in the OEM’s machine does meet CE, the
machine will not necessarily meet CE as a machine.
Using CE-approved wiring practices (like proper shielding) and the filters
should assure the drive will meet EN55014 (1993 emissions standard) and
EN50082-1 (1992 immunity standard).
