3.4.3. EMC Immunity

In order to document immunity against electrical interference from electrical phenomena, the
following immunity tests have been made on a system consisting of a frequency converter (with
options, if relevant), a screened control cable, and a control box with potentiometer, motor cable,
and motor.
The tests were performed in accordance with the following basic standards:
