7.13.3 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 office environment. All Danfoss drives comply with the
requirements for both the industrial and the home/office 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 7.17 .
•
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 field radiation, amplitude modulated simulation of the
effects 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 effect from radio-transmission equipment
joined by connection cables.
