Compliance with various system level guidelines:
The harmonic current data in the table are given in
accordance with IEC/EN61000-3-12 with reference to the
Power Drive Systems product standard. They may be used
as the basis for calculation of the harmonic currents'
influence on the power supply system and for the
documentation of compliance with relevant regional
guidelines: IEEE 519 -1992; G5/4.
2.9.7 Immunity Requirements
The immunity requirements for adjustable frequency drives
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 adjustable frequency drives
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.
In order to document immunity against electrical
interference from electrical phenomena, the following
immunity tests have been made on a system consisting of
a Adjustable frequency drive (with options if relevant), a
shielded control cable and a control box with potenti-
ometer, 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): Electrical
interference: 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.
