9.2.3 Site altitude

The components can be operated up to a site altitude of 1000 m amsl without power reduction.

• From 1000 ... 4000 m amsl there is a power reduction.

• For inverters the derating factor is stored in the DSD device-specifically.

• The site altitude for geared motors is considered as a function of the temperature:

• For motors without a gearbox, the following applies:
