Current derating as a function of installation altitude
If the converters are operated at an installation altitude > 2000 m above sea level, the maximum permissible output
current can be calculated using the following tables according to the degree of protection selected for the cabinet. To
obtain these values, the air flow rate stipulated in the technical data tables must be provided. The specified values
already include a permitted correction between installation altitude and ambient temperature (incoming air
temperature at the inlet to the converter cabinet).

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.
