IPE300 series engineering VFD Technical data
-337-
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.
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.
B.6.1 VFD category of C2
The induction disturbance limit meets the following stipulations:
1. Select an optional EMC filter
according to Appendix E “Optional peripheral accessories” and
install it following the description in the EMC filter manual.
2. Select the motor and control cables according to the description in the manual.
3. Install the VFD according to the description in the manual.
4. For the maximum length of the motor cable, see section "EMC compatibility and motor cable
length".
 The VFD may generate radio interference, you need to take measures to reduce
the interference.
B.6.2 VFD category of C3
The anti-interference performance of the VFD meets the requirements of the second environment in
the IEC/EN 61800-3 standard.
The induction disturbance limit meets the following stipulations:
1.
Select an optional EMC filter according to Appendix E “Optional peripheral accessories” and
install it following the description in the EMC filter manual.
2. Select the motor and control cables according to the description in the manual.
3. Install the VFD according to the description in the manual.
4. For the maximum length of the motor cable, see section "EMC compatibility and motor cable
length".
 VFDs of category C3 cannot be applied to civilian low-voltage common grids.
When applied to such grids, the VFDs may generate radio frequency
electromagnetic interference.
