Explanatory notes for EN 61800-3+A11
The EN 61800-3+A11 product standard for "Adjustable speed electrical power drive
systems, Part 3: EMC requirements and specific test methods" specifies limit values for
noise radiation and interference immunity. The EMC product standard EN 61800-3+A11
does not apply directly to a frequency converter but to a complete drive system, which
comprises the complete circuitry, motor and cables in addition to the converter.
