Derating data
Current derating as a function of the site altitude and ambient temperature
If the cabinet units are operated at a site altitude >2000 m above sea level, the maximum
permissible output current can be calculated using the following tables. The site altitude and
ambient temperature are compensated here. The degree of protection selected for the
cabinet units must also be taken into account.

and site altitude for cabinet units with degree of protection IP20/IP21/IP23/IP43
