Power Drive Systems product standard. The data may be
used to calculate the harmonic currents' influence on the
power supply system and to document compliance with
relevant regional guidelines: IEEE 519 -1992; G5/4.
2.9.6 Immunity Requirements
The immunity requirements for frequency converters
depend on the environment where they are installed. The
requirements for the industrial environment are higher
than the requirements for the home and office
environment. All Danfoss frequency converters comply
with the requirements for the industrial environment and
consequently comply also with the lower requirements for
home and office environment with a large safety margin.
To document immunity against electrical interference from
electrical phenomena, the following immunity tests have
been made in accordance with 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

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.
