5 Monitoring the ambient air temperature
Operate the device below the specified maximum ambient air temperature 
exclusively.
See “General technical data” on page 49.
The ambient air temperature is the temperature of the air at a distance of 2 in 
(5 cm) from the device. It depends on the installation conditions of the device, 
e.g. the distance from other devices or other objects, and the output of 
neighboring devices.
The temperature displayed in the CLI and the GUI is the internal temperature 
of the device. It is higher than the ambient air temperature. The maximum 
internal temperature of the device named in the technical data is a guideline 
that indicates to you that the maximum ambient air temperature has possibly 
been exceeded.
