Application notes
9.1
Installation altitude and ambient temperature
Convection-cooled motors
The performance data specified for the drive system applies to
●
Ambient temperatures from 0 ºC to +40 ºC
(+5 °C to +40 °C for liquid-cooled motors)
●
Installation altitudes from 0 m to 1000 m above sea level
When using these drive systems outside these ranges, reduce the perform‐
ance data according to the following illustration.

Load factors/derating
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 the reduced data are not exceeded by your application.
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.
Ensure that your application does not exceed the reduced motor data.
The maximum allowed installation altitude of the motors above
MSL is
●
3000 m in case of stators with housing and device connector
or terminal box
●
5000 m in case of stators with connection cable
