Power derating
4.2.1
Version: 1.7
Derating may be necessary at high ambient temperature or when
operating at a great height above sea level. Continuous forces are
affected by the reduction.
Ambient temperature
f
= Temperature utilization factor
T
t
= Ambient temperature in °C
A
Calculation of the power data when exceeding the specified temper-
ature limit > 40°C:
F
= F
x f
CA_red

T
Installation altitude
f
= Altitude utilization factor
H
h = Altitude in meters
Calculation of the performance data if the installation altitude ex-
ceeds 1000 m:
F
= F
x f
