2.10.4. EMC Immunity
In order to document immunity against interference from electrical phenomena, the following
immunity tests have been performed on a system consisting of an adjustable frequency drive (with
2
options, if relevant), a shielded control cable and a control box with potentiometer, motor cable
and motor.
The tests were performed in accordance with the following basic standards:
•
