The typical power loss is at nominal load conditions and expected to be within
±
15% (tolerance relates to variety
in voltage and cable conditions).
The losses are based on the default switching frequency. The losses increase significantly at higher switching
frequencies.
The options cabinet adds weight to the frequency converter. The maximum weights of the D5h–D8h frames is
shown in
