EMC Immunity
In order to document i mmunity against electrical interference from electrical p henomena, the following
immunity tests have been carried out on a system consisting of an adjustable frequency drive (with options,
if relevant), a shielded control cab le, and a control box with potentiometer, mo tor cable, and m o tor.
The tests w ere per formed in accordance with the following basic standards:
• EN 61000-4-2 (IEC 61000-4-2): Electrostatic discharges (ESD)
Simulation of electrostatic discharges from human beings.
• EN 610 00 - 4-3 (IEC 61 000-4-3): Incoming electromagnetic field radiation, am plitude modulated
Simulation of the effec ts of radar and radio communication equipment as well as mobile communications.
• EN 61000-4-4 (IEC 61000-4-4): Transients
Simulation of interference broug h t about by switching with a contactor, relays, or similar devic es.
• EN 61000-4-5 (IEC 61000-4-5): Surge transients
Simulation of transients brought about e.g. by lightning that strikes near installations.
• EN 61000-4-6 ( IEC 61000-4-6): RF Common mode
Simulation of the effect from radio-transmitting equipment connected to connectio n cables.
