Installation positions with active cooling (fan):
The maximum ambient temperature for CPU modules mounted on a top-hat rail is 50°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 and two incorrect installation positions. Observe minimum clearance! Mounting must provide a clearance of 30 mm both above and below a CX1020/CX1030 device combination to ensure adequate ventilation of the base CPU module and the power supply unit.
Correct installation position:
The high-performance CX1020/CX1030 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.
Incorrect installation positions:
The CX1020/CX1030 system must not be operated vertically on the top-hat rail. A vertical position would lead to insufficient CPU ventilation, since the ventilation openings are located on the top and bottom of the housing. Installation of the system on its side would also lead to inadequate ventilation.
The installation position "backside down" is only allowed with the right power supply. The power supply should have a cooling plate (CX1100-001x).
