Comments
Observe the following "Derating" table and any load-
dependent limitations.
Refer to the documentation of the employed compo‐
nent.
The cooling effect of air depends on the density of the
air. The locally occurring air pressure (operating alti‐
tude) might restrict the maximum permissible ambi‐
ent temperature. The density of the air decreases with
increasing altitude.
