■ 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 VLT 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.

EN 55011:

Threshold values and measuring

methods for radio interference from industrial,

scientific and medical (

ISM) high frequency

equipment.
