9.3 Installation altitude and ambient conditions
The motor performance data specified are applicable for
●
Ambient temperature 0 ... +40 °C
● Setup elevation of up to 1,000 m above sea level.
Different conditions lead to a departing of the data according to the following
diagrams. Do occur deviating ambient temperatures and higher installation
altitude at the same time, both utilization factors must be multiplied.
① Usability to capacity, depending on the surrounding air temper‐
ature
② Usability to capacity, depending on the installation altitude

The details for the utilization depending from the installation alti‐
tude and environmental temperature do not only apply to the mo‐
tor , but on the whole drive system, consisting of motor, drive con‐
troller and mains supply. Ensure that the reduced data are not ex‐
ceeded by your application.
