Introduction
To document immunity against electrical interference from
electrical phenomena, the following immunity tests have
been made on a system consisting of a frequency
2 2
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
Voltage range: 380-480 V, 525-600 V, 525-690 V

•
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 for
example, by lightning that strikes near instal-
lations.

EN 61000-4-6 (IEC 61000-4-6): RF Common
mode: Simulation of the effect from radio-
transmission equipment joined by connection
cables.
