With the DF6-340-37K to DF6-340-132K frequency inverters, fit
the radio interference filters on the side next to the device (book-
type mounting). You can fit the RFI filter either to the left or the
right of the frequency inverter.
Radio interference filters produce leakage currents which, in the
event of a fault (phase failure, load unbalance), can be larger than
the rated values. To prevent dangerous voltages, the filters must
therefore be earthed before use. As the leakage currents are high-
frequency interference sources, the earthing connections and
cables must have a low resistance and large contact surfaces.
