■ EMC Immunity
In order to document immunity against interference
from switched electrical phenomena, the following
immunity test has been made on a system consist-
ing of a frequency converter, a screened/armoured
control cable and a control box with potentiometer,
screened/armoured motor cable, screened/armoured
brake cable and an LCP with a cable.
The tests were performed in accordance with the fol-
lowing basic standards:
• EN 61000-4-4 (IEC 1000-4-4): Burst transients
Simulation of interference brought about by
switching with contactors, relays or similar de-
vices.
• EN 61000-4-5 (IEC 1000-4-5): Surge transients
Simulation of transients brought about e.g. by
lightning that strikes near installations.
• EN 61000-4-2 (IEC 1000-4-2) : Electrostatic
discharges (ESD)
Simulation of electrostatic discharges from hu-
man beings .
• EN 61000-4-3(IEC 1000-4-3): Incoming electro-
magnetic field radiation, amplitude modulated.
Simulation of the effects of radar and radio broad-
cast devices as well as mobile communication
devices.
• VDE 0160 class W2 test pulse: Mains tran-
sients
Simulation of high-energy transients generated by
breaks in master fuses, connection to phase ad-
vancer batteries and the like.
• EN 61000–4–6: Cable-borne HF
Simulation of the effect from radio-transmitting
equipment connected to connection cables.
