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 relevant), 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): Simulation of electrostatic
discharges from human beings.
•
EN 61000-4-3 (IEC 61000-4-3): Incoming electro-
magnetic 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 61000-4-4): Burst transients:
Simulation of interference brought about by
switching a contactor, relay or similar devices.
•
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-transmission
equipment joined by connection cables.
