EMC test results
Emission
Subsequent test results have been obtained using a
system with a VLT
frequency converter (with RFI filter
module) a screened control cable and control box
with potentiometer, unscreened motor cable and mo-
tor.
With the purpose of minimising the cable-conducted
interference to the mains supply and the radiated
interference from the frequency converter system, the
motor cables should be kept as short as possible.
According to experience, most installations represent
only a slight risk of any interference from radiation.
