EMC ImmunityIn order to document immunity against electrical interference from electrical phenomena, the followingimmunity tests have been made on a system consisting of an adjustable frequency drive (with options, ifrelevant), 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:ï EN 61000-4-2 (IEC 61000-4-2): Electrostatic discharges (ESD)Simulation of electrostatic discharges from human beings.ï EN 61000-4-3 (IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude modulatedSimulation of the effects of radar and radio communication equipment as well as mobile communications.ï EN 61000-4-4 (IEC 61000-4-4): Electrical interferenceSimulation of interference brought about by switching with a contactor, relays, or similar devices.ï EN 61000-4-5 (IEC 61000-4-5): Surge transientsSimulation of transients brought about, e.g., by lightning that strikes near installations.ï EN 61000-4-6 (IEC 61000-4-6): RF Common modeSimulation of the effect from radio-transmitting equipment connected to connection cables.See following EMC immunity form.43MG.33.B6.22 - VLT is a registered Danfoss trademark
