Note the permissible installation positions
Notice | |
Increased heat generation If the minimum distances are not observed, the power supply unit and the Embedded PC may overheat.
|
Note the following specifications for the control cabinet:
- Maintain the permissible ambient temperature in the vicinity of the power supply unit and embedded PC. 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 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 CX2100-0914 power supply unit and the embedded PC are mounted horizontally on the mounting rail as standard. A vertical or horizontal installation position is only possible if the embedded PC is actively cooled.

Horizontal installation position
Maintain the ambient temperatures. In addition, a minimum clearance of 30 mm above and below the cooling fins of the embedded PCs is required in order to ensure adequate ventilation. This ensures optimum air flow through the cooling fins of the embedded PC.
If there is a risk of vibrations or impact in the same direction as the mounting rail when the embedded PC is installed horizontally, the device must be secured with an additional bracket in order to prevent it slipping.
Vertical installation position
Maintain the ambient temperatures. The minimum distance of at least 30 mm above and below the cooling fins of the embedded PC must also be adhered to when the device is mounted vertically.
Ensure that any bus terminals connected to the embedded PC are designed for operation in vertical position.
If you install the embedded PC vertically, the device must be fastened properly to prevent it slipping off the DIN rail. Install a bracket below the embedded PC for this purpose.
Horizontal installation position
Maintain the ambient temperatures. The minimum distance of at least 30 mm above and below the cooling fins of the embedded PC must also be adhered to when the device is mounted horizontally.
Ensure that any bus terminals connected to the embedded PC are designed for operation in horizontal position.
If there is a risk of vibrations or impact in the same direction as the mounting rail when the embedded PC is installed horizontally, the device must be secured with an additional bracket in order to prevent it slipping.
