Danfoss VLT Decentral Drive FCD 302 Design Manual page 17

Product Overview
In order to document immunity against electrical
interference from electrical phenomena, the following
immunity tests have been made on a system consisting of
2 2
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
Voltage range: 200-240 V, 380-480 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 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.
