EMC Immunity

In order to document immunity against electrical interference from electrical phenomena, the following
immunity tests have been made on a system consisting of a frequency converter (with options, if rele-
vant), a screened control cable, and a control box with potentiometer, motor cable, and motor.
The tests were performed in accordance with the following basic standards:
• EN 61000-4-2 (IEC 61000-4-2): Electrostatic discharges (ESD)
discharges from human beings.
• EN 61000-4-3 (IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude
modulated Simulation of the effects of radar and radio communication equipment as well as
mobile communications.
• EN 61000-4-4 (IEC 61000-4-4): Burst transients
by switching with a contactor, relays, or similar devices.
• EN 61000-4-5 (IEC 61000-4-5): Surge transients
lightning that strikes near installations.
• EN 61000-4-6 (IEC 61000-4-6): RF Common mode
transmitting equipment connected to connection cables.
See following EMC immunity form.
