Goodrive18 series two-in-one VFD Technical data
-142-
Category II: All environments except those in Category I.
VFD categories:
C1: Rated voltage lower than 1000 V, applied to enviroments 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.
C3: Rated voltage lower than 1000 V, applied to environments of Category II. They cannot be
applied to environments of Category I.
The induction disturbance limit meets the following stipulations:
Select an optional EMC filter according to Appendix D and install it following the
description in the EMC filter manual.
Select the motor and control cables according to the description in the manual.
Install the VFD according to the description in the manual.
VFDs in category C3 cannot be used on civilian low voltage grids.
Otherwise, radio frequency electromagnetic interference will result.
C4: Rated voltage higher than 1000 V, or rated current higher or equal to 400 A, applied to
complex systems in environments of Category II.
