l 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.
l EN 61000-4-4 (IEC 61000-4-4): Burst transients: Simulation of interference brought about by switching a contactor, relay, or similar
devices.
l EN 61000-4-5 (IEC 61000-4-5): Surge transients: Simulation of transients brought about by lightning strikes near installations.
l EN 61000-4-6 (IEC 61000-4-6): RF common-mode: Simulation of the effect from radio-transmission equipment joined by connection
cables.

7.13.5 EMC Compatibility
NOTICE
OPERATOR RESPONSIBILITY
According to the EN 61800–3 standard for variable-speed drive systems, the operator is responsible for ensuring EMC compliance.
Manufacturers can offer solutions for operation conforming to the standard. Operators are responsible for applying these
solutions, and for paying the associated costs.
There are 2 options for ensuring electromagnetic compatibility.
l Eliminate or minimize interference at the source of emitted interference.
l Increase the immunity to interference in devices affected by its reception.
