Installation altitude and ambient temperature

The stated performance data of the motors are valid according to DIN EN
60034‑1 for:
● Ambient temperature 0 ... 40 °C
● Installation altitude 0 ... 1000 m above sea level
If the specified limits are exceeded, the performance data of the motors must
be reduced.

Fig. 9-1: Derating of ambient temperature, installation altitude (in operation)
Calculation of performance data in case the limits specified are exceeded:
Ambient temperature > 40 °C
M = M ×f
0_red 0 T
Installation altitude > 1,000 m
M = M ×f
0_red 0 H
Ambient temperature > 40 °C and setup elevation > 1,000 m
M = M ×f ×f
0_red 0 T H
