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.
Limit values for compliance with EN 61800-3 Category C3
The following table lists the key limit values for compliance with EN 61800-3 on devices with
restricted availability
for a drive system in accordance with Category C3 (Category C3: Drive
system (PDS) with a rated voltage of < 1000 V. For use in a second environment), i.e.,
use
in second environment
(industrial) with commissioning and installation carried out by an
EMC expert.
