■ EMC Immunity
In order to confirm immunity against interference from electrical phenomena, the following immunity test has
been made on a system consisting of a frequency converter (with options, if relevant), a screened/armoured
control cable and control box with potentiometer, motor cable and motor.
The tests were made in accordance with the following basic standards:
EN 61000-4-2 (IEC 1000-4-2): Electrostatic discharges (ESD)
Simulation of electrostatic discharges from human beings.
EN 61000-4-3 (IEC 1000-4-3): Incoming electromagnetic field radiation, amplitude modulated
Simulation of the effects of radar and radio communication equipment as well as mobile communications
equipment.
EN 61000-4-4 (IEC 1000-4-4): Burst transients
Simulation of interference brought about by switching with a contactor, relays or similar devices.
EN 61000-4-5 (IEC 1000-4-5): Surge transients
Simulation of transients brought about e.g. by lightning that strikes near installations.
ENV 50204: Incoming electromagnetic field, pulse modulated
Simulation of the impact from GSM telephones.
ENV 61000-4-6: Cable-borne HF
Simulation of the effect of radio transmission equipment connected to supply cables.
VDE 0160 class W2 test pulse: Mains transients
Simulation of high-energy transients brought about by main fuse breakage, switching of power
factor-correction capacitors, etc.
