10 Operating conditions and application notes
10.1 Environmental conditions
10.1.1 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.
