Derating data

Permissible output current as a function of the ambient temperature
The cabinet devices and the associated system components are rated for an ambient
temperature of 40 °C and installation altitudes up to 2000 m above sea level. The output
current must be reduced if the cabinet devices are operated at ambient temperatures above
40 °C. Ambient temperatures above 50 °C are not permissible. The following tables specify
the permissible output current as a function of the ambient temperature for the different
degrees of protection .

cabinet unit) and installation altitude for cabinet units with degree of protection IP20/IP21/IP23/IP43

Installation altitudes between 2000 m and 5000 m above sea level
If the SINAMICS G150 cabinet units are operated at an installation altitude >2000 m above
sea level, it must be taken into account that the air pressure and, consequently, the air
density decreases. The lower air density also reduces the cooling efficiency and the
insulation capacity of the air.
