Derating data
12.2.1.1
Current derating as a function of the ambient temperature
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 .
