To document immunity against burst transient from electrical phenomena, the following immunity tests have been made on a system
consisting of:
A drive (with options if relevant).
l
A shielded control cable.
l
A control box with potentiometer, motor cable, and motor.
l
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.
l
EN 61000-4-3 (IEC 61000-4-3) Radiated immunity: Amplitude modulated simulation of the effects of radar and radio
l
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.
l
EN 61000-4-5 (IEC 61000-4-5) Surge transients: Simulation of transients caused by, for example, lightning that strikes near
l
installations.
EN 61000-4-6 (IEC 61000-4-6) Conducted immunity: Simulation of the effect from radio-transmission equipment joined by
l
connection cables.
The immunity requirements should follow product standard IEC 61800-3. See
Table 36: EMC Immunity
