must be installed and operated by specialized personnel when applied to the first environment
Note: The EMC standard IEC/EN 61800-3 no longer restricts the power distribution of inverters, but it
specifies their use, installation, and commissioning. Specialized personnel or organizations must
have the necessary skills (including the EMC-related knowledge) for installing and/or performing
commissioning on the electrical drive systems.
C3: Rated voltage lower than 1000 V, applied to the second environment. They cannot be applied to
the first environment.
C4: Rated voltage higher than 1000 V, or rated current higher or equal to 400 A, applied to complex
systems in the second environment.
