B.5.1 CE marking
The CE marking on the name plate of a VFD indicates that the VFD is CE-compliant, meeting the
regulations of the European low-voltage directive (2014/35/EU) and EMC directive (2014/30/EU).
B.5.2 UL and CUL marking
The UL and CUL markings are attached to the VFD, indicating that the VFD follows the provisions of
UL508C and C22.2 No. 274-13.
B.5.3 EMC compliance declaration
European union (EU) stipulates that the electric and electrical devices sold in Europe cannot generate
electromagnetic disturbance that exceeds the limits stipulated in related standards, and can work
properly in environments with certain electromagnetic interference. The EMC product standard (EN
61800-3:2004) describes the EMC standards and specific test methods for adjustable speed
electrical power drive systems. Our products have been compliant with these EMC regulations.
B.6 EMC regulations
The EMC product standard (EN 61800-3) describes the EMC requirements on VFDs.
Application environment categories
Category I: Civilian environments, including application scenarios where VFDs are directly connected
to the civil power supply low-voltage grids without intermediate transformers
Category II: All environments except those in Category I.
VFD categories
C1: Rated voltage lower than 1000 V, applied to environments of Category I.
C2: Rated voltage lower than 1000 V, non-plug, socket, or mobile devices; power drive systems that
must be installed and operated by specialized personnel when applied to environments of Category I
Note: The EMC standard IEC/EN 61800-3 no longer restricts the power distribution of VFDs, 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.
