Measured using 5 m screened motor cables at rated load and rated frequency
4)
The typical power loss is at normal load conditions and expected to be within
±
15% (tolerance relates to variety in voltage and cable
conditions).
Values are based on a typical motor efficiency (eff2/eff3 border line). Lower efficiency motors will also add to the power loss in the frequency
converter and vice versa.
If the switching frequency is raised from nominal the power losses may rise significantly.
LCP and typical control card power consumptions are included. Further options and customer load may add up to 30 W to the losses. (Though
typically only 4 W extra for a fully loaded control card or options for slot A or slot B, each).
Although measurements are made with state of the art equipment, some measurement inaccuracy must be allowed for (
±
5%).

(A2+A3 may be converted to IP21 using a conversion kit. (See also Mechanical mounting and IP21/Type 1 Enclosure kit in the Design Guide.))

(B3+B4 and C3+C4 may be converted to IP21 using a conversion kit. (See also items Mechanical mounting and IP21/Type 1 Enclosure kit in the
Design Guide.))
