Armature Filters
If the end-user is not using a CE-approved motor, a filter
on the armature must also be used. See Table 4 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!
