EMC ImmunityIn order to document immunity against electrical interference, the following immunity tests have been made on asystem consisting of a frequency converter, a screened/armoured control cable and a control box with potenti-ometer, screened/armoured motor cable, screened/armoured brake cable and an LCP 2 with a cable.The tests were performed in accordance with the fol-lowing basic standards:• EN 61000-4-4 (IEC 61000-4-4): Burst transients Simulation of interference brought about by switchingwith contactors, relays or similar devices.• EN 61000-4-5 (IEC 61000-4-5): Surge transients Simulation of transients brought about e.g. by lightningthat strikes near installations.• EN 61000-4-2 (IEC 61000-4-2) : Electrostatic discharges (ESD)Simulation of electrostatic dischargesfrom human beings.• EN 61000-4-3(IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude modula-ted.Simulation of the effects of radar and radio broadcast devices as well as mobile communicationdevices.• VDE 0160 class W2 test pulse: Mains transients Simulation of high-energy transients generated bybreaks in master fuses, connection to phase advancer batteries and the like.• EN 61000-4-6 (IEC 61000-4-6): RF Common mode Simulation of the effect from radio-transmittingequipment connected to connection cables.See following EMC immunity form.140 MG.27.E2.02 - VLT is a registered Danfoss trademark
