9.1.1

Installation altitude and ambient temperature

The motor performance data specified are applicable for
● Ambient temperatures ranging from 0 °C to +40 °C,
● Installation altitudes from 0 m to 1000 m above sea level
The performance data of motors used outside of the above ranges is reduced
according to the following figure.
① Usability to capacity, depending on the surrounding air temper‐
ature
② Usability to capacity, depending on the installation altitude
f Temperature utilization factor
T
t Ambient temperature in degrees Celsius
A
f Height utilization factor
H
h Installation altitude in meters
Fig. 9-1: Utilization factors
If either the ambient temperature or the installation altitude is above the nomi‐
nal data:
1. Multiply the motor data specified in the selection data by the determined
utilization factor.
2. Ensure that your application does not exceed the reduced motor data.
If both the ambient temperature and the installation altitude exceed the nomi‐
nal data:
1. Multiply the determined utilization factors f
2. Multiply the resulting value by the motor data specified in the selection
data.
3. Ensure that your application does not exceed the reduced motor data.
