10.14.3 Immunity Requirements
The immunity requirements for drives depend on the installation environment. The requirements for the industrial
environment are higher than the requirements for the home and oce environment. All Danfoss drives comply with the
requirements for both the industrial and the home/oce environment.
To document immunity against burst transient, the following immunity tests have been performed on a drive (with options
if relevant), a shielded control cable, and a control box with potentiometer, motor cable, and motor. The tests were
performed in accordance with the following basic standards. For more details, see Table 10.40.
•
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 electromagnetic
eld radiation, amplitude modulated simulation of the
eects of radar, radio communication equipment, and 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 by lightning strikes near
installations.
•
EN 61000-4-6 (IEC 61000-4-6): RF common mode: Simulation of the eect from radio-transmission equipment
joined by connection cables.
