Warning
The maximum ambient temperature for CPU modules mounted on a top-hat rail is 55°C. The
orientation in which the device is fitted must be selected in such a way that cooling air can flow
vertically through the ventilation holes. The images show the correct installation position.
Observe minimum clearance!
Mounting must provide a clearance of 30 mm both above and below a CX-System device
combination to ensure adequate ventilation of the base CPU module and the power supply unit.
Correct installation position:
The high-performance CX9000 system generates a significant amount of heat, which is dissipated via a passive
ventilation system. This system requires the unit to be mounted correctly. Ventilation openings are located at the top
and bottom of the housing. The system therefore has to be installed horizontally. This ensures optimum air flow.
