To document immunity against burst transient from electrical phenomena, the following immunity tests have been carried out on a
system consisting of:
A drive (with options if relevant).
A shielded control cable.
A control box with potentiometer, 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) Radiated immunity: Amplitude modulated simulation of the eects of radar and radio communi-
cation 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, for example, lightning that 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 con-
nection cables.
The immunity requirements should follow product standard IEC 61800-3. See
Table 94.
