AC Line Filters
In addition to EMI/RFI safeguards inherent in the MMRG design,
external filtering is required.
Minarik requires the Corcom
®
AC line filters listed in Table 3, as
well as a line-to-line capacitor connected between L1 and L2. The
capacitor must be rated at 2.2 microfarads and 250 volts minimum.
Use model 5VV1 with drives rated for 3 ADC or below, and model
20VV1 with drives rated for 10 ADC or below.

Wire the AC line filter within 0.25 meters of the drive.
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!
Use of a CE-approved motor, the correct filter from Table 3, in
addition to the line-to-line capacitor, is all that is necessary to meet
the EMC directives listed herein.
