2.10.4. 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:
• EN 61000-4-2 (IEC 61000-4-2): Electrostatic discharges
• EN 61000-4-3 (IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude
and radio communication equipment as well as mobile communications.
• EN 61000-4-4 (IEC 61000-4-4): Burst
devices.
• EN 61000-4-5 (IEC 61000-4-5): Surge
• EN 61000-4-6 (IEC 61000-4-6): RF Common
cables.
See following EMC immunity form.
