Siemens SINAMICS G220 - Permissible Output Current Depending on the Installation Altitude and Ambient Temperature, IP55

17.5 Permissible output current depending on the installation
altitude and ambient temperature, IP55
Technical data
The permissible output current of the converter depends on the installation altitude and the
ambient temperature.
Continuous operation above the permissible output current leads to a converter malfunction
due to overtemperature.
