2.9.3 Immunity RequirementsThe immunity requirements for frequency convertersdepend on the environment where they are installed. Therequirements for the industrial environment are higherthan the requirements for the home and officeenvironment. All Danfoss frequency converters complywith the requirements for the industrial environment andconsequently comply also with the lower requirements forhome and office environment with a large safety margin.To document immunity against burst transient fromelectrical phenomena, the following immunity tests havebeen made on a system consisting of a frequencyconverter (with options if relevant), a shielded controlcable, and a control box with potentiometer, motor cable,and motor.:The tests were performed in accordance with the followingbasic standards• EN 61000-4-2 (IEC 61000-4-2): Electrostaticdischarges (ESD): Simulation of electrostaticdischarges from human beings.• EN 61000-4-3 (IEC 61000-4-3): Incoming electro-magnetic field radiation, amplitude modulatedsimulation of the effects of radar and radiocommunication equipment and mobile communi-cations equipment.• EN 61000-4-4 (IEC 61000-4-4): Burst transients:Simulation of interference brought about byswitching a contactor, relay, or similar devices.• EN 61000-4-5 (IEC 61000-4-5): Surge transients:Simulation of transients brought about forexample, by lightning that strikes near instal-lations.• EN 61000-4-6 (IEC 61000-4-6): RF commonmode: Simulation of the effect from radio-transmission equipment joined by connectioncables.See Table 2.16.Voltage range: 200–240 V, 380–480 VBasic standard BurstIEC 61000-4-4SurgeIEC 61000-4-5ESDIEC61000-4-2Radiated electromagneticfieldIEC 61000-4-3RF commonmode voltageIEC 61000-4-6Acceptance criterion B B B A ALine 4 kV CM 2 kV/2 Ω DM4kV/12 Ω CM — — 10 VRMSMotor 4 kV CM 4 kV/2 Ω1) — — 10 VRMSBrake 4 kV CM 4 kV/2 Ω1) — — 10 VRMSLoad sharing 4 kV CM 4 kV/2 Ω1) — — 10 VRMSControl wires 2 kV CM 2 kV/2 Ω1) — — 10 VRMSStandard bus 2 kV CM 2 kV/2 Ω1) — — 10 VRMSRelay wires 2 kV CM 2 kV/2 Ω1) — — 10 VRMSApplication and fieldbusoptions 2 kV CM 2 kV/2 Ω1) — — 10 VRMSLCP cable 2 kV CM 2 kV/2 Ω1) — — 10 VRMSExternal 24 V DC 2 V CM 0.5 kV/2 Ω DM1 kV/12 Ω CM — — 10 VRMSEnclosure — — 8 kV AD6 kV CD 10 V/m —Table 2.16 EMC Immunity1) Injection on cable shieldAD: Air DischargeCD: Contact DischargeCM: Common ModeDM: Differential ModeProduct Overview and Functi...
