Emission:
Subsequent test results have been ob-
tained using a system with a VLT
®
fre-
quency converter (with options, if relevant),
a screened control cable and control box
with potentiometer, screened motor cable
and motor.
With the purpose of minimising the cable-borne 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.
