12 Notes Regarding Application
12.1 Conditions of use
Maximum installation elevation and ambient temperature
The power data of the motor apply :
· an ambient temperature range of 0º to +40º C
· and an installation elevation of 0 to 1000 meters above sea level
If the motor is to be used above this range, then the “load factors” must
be taken into consideration. This derates the output data.

Fig. 12-1: MKE load factors
If either ambient temperature or installation elevation exceed nominal
ratings, then:
Multiply the “continuous standstill torque ” listed in the selection data with
the determined load factor.
Make sure that the derated torque is not exceeded by your application.
If both ambient temperature and the installation elevation exceed
nominal ratings then :
Multiply the determined load factors f
T and fH .
Multiply the determined value by the “continuous standstill torque” of the
motor indicated in the selection data.
Make sure that the derated torque is not exceeded by your application.
