Note the permissible installation positions
NOTE
Overheating
The Embedded PC may overheat if the installation position is incorrect or the minimum distances 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 mounting rail, in order to ensure optimum
heat dissipation. Only Embedded PCs with active cooling can be operated vertically or horizontally.

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 distances of 30 mm above and below the Embedded PCs.
• 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.
Permitted installation position without fan
The Embedded PC must be installed horizontally on the mounting 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 PCs is required, in
order to ensure adequate ventilation.

If vibrations and impact occurs in the same direction as the mounting rail, the Embedded PC must be
secured with an additional bracket, in order to prevent it slipping.
