Efficiency levels by model can be found in the ”WEG Ecodrive” app available for Android and iOS devices.
(6)
For DC power supply, an external pre-charge circuit must be used. Exception: in CFW900 inverters with frames A, B and C, it is possible to
connect the ”+” terminal of the DC power supply to the DC+ terminal and the ”-” terminal to the R/L1/L and S/L2/N terminals. In this case,
it is not necessary to use an external pre-charge.

For applications with common DC link, please consult WEG.
