2.6.3 EMC Immunity Requirements
The immunity requirements for frequency converters depend on the environment in which they are installed. The
requirements for the industrial environment are higher than the requirements for the home and oce environment. All
Danfoss frequency converters comply with the requirements for the industrial environment. Therefore, they also comply with
the lower requirements for home and oce environment with a large safety margin.
To document immunity against burst transient from electrical phenomena, the following immunity tests have been made on
a system consisting of:
•
A frequency converter (with options if relevant)
•
A shielded control cable
•
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) Radiated immunity: Amplitude modulated simulation of the
eects of radar and
radio communication equipment and mobile communications equipment.
•
EN 61000-4-4 (IEC 61000-4-4) Burst transients: Simulation of interference caused by switching a contactor, relay,
or similar devices.
•
EN 61000-4-5 (IEC 61000-4-5) Surge transients: Simulation of transients caused by, for example, lightning that
strikes near installations.
•
EN 61000-4-6 (IEC 61000-4-6) Conducted immunity: Simulation of the
eect from radio-transmission equipment
joined by connection cables.
The immunity requirements should follow product standard IEC 61800-3 and Danfoss internal standards. See Table 2.13 for
details.
