Power derating - temperature
5–45 °C (41–113 °F) without derating. 45–60 °C (113–140 °F) with derating 1.5% per °C. See
Illustration 7.1.
Power derating - altitude above sea level 1000 m (3280 ft) without derating. 1000–4000 m (3280–13123 ft) with derating 5% per 1000 m
(3280 ft).
Table 7.1 General Technical Data
1) THDi level is system level performance from the lter combined with the actual frequency converter.
NOTICE
The reduction of the low harmonic current emission to the rated THDi implies that the THDv of the non-inuenced
mains voltage is lower than 2%, and the ratio of short circuit power to installed load (R
SCE
) is above 66. Under these
conditions, the THDi of the mains current of the frequency converter is reduced to 10% or 5% (typical values at nominal
load). If these conditions are not or only partially fullled, a signicant reduction of the harmonic components can still
be achieved, but the rated THDi values may not be observed.
