Current derating as a function of installation altitude/ambient temperature
If the SINAMICS G130 converters are operated at an installation altitude of >2000 m above sea level, the maximum
permissible output current can be calculated using the following tables. The specified values already include a
permitted correction between installation altitude and ambient temperature (incoming air temperature at the inlet to
the Power Module).

Current derating as a function of the ambient temperature (inlet air temperature) and installation altitude
To obtain these values, the air flow rate stipulated in the technical data tables must be provided. Particular attention
must be paid to ensuring that no thermal short circuits occur either outside or inside the cabinet. The top of the
cabinet must be designed such that heated outlet air can exit.
Voltage derating as a function of installation altitude
In addition to current derating, voltage derating as stipulated in the table below is applicable at installation altitudes of
> 2000 m above sea level.
