Permissible installation positions
Notice | |
Overheating The embedded PC may overheat if the installation position is incorrect or the minimum gaps are not adhered to. Adhere to the maximum ambient temperature of 60° C and the mounting instructions. |
Install the embedded PC horizontally in the control cabinet on a DIN rail, in order to ensure optimum heat dissipation.
Note the following specifications for the control cabinet:
- The embedded PC should only be operated at ambient temperatures between -25 °C and 60 °C. Measure the temperature below the embedded PC at a distance of 30 mm to the cooling fins, in order to determine the ambient temperature correctly.
- Adhere to the minimum gaps of 30 mm above and below the embedded PC.
- Additional electrical equipment affects the heat generation in the control cabinet. Select a suitable control cabinet enclosure depending on the application, or ensure that excess heat is dissipated from the control cabinet.
The embedded PC must be mounted horizontally on the DIN rail. Ventilation openings are located at the top and bottom of the housing. This ensures an optimum airflow through the embedded PC in vertical direction. In addition, a minimum clearance of 30 mm above and below the embedded PC is required, in order to ensure adequate ventilation.

Installation position with limited temperature range up to 50 °C
You can also mount the Embedded PC horizontally on the mounting rail. Note that you can then only operate the Embedded PC in this installation position up to an ambient temperature of 50 °C.
