Mounting and wiring
CX8030 / CX803122 Version: 1.6
Attention
Comply with the permitted installation position and minimum distances!
The maximum ambient temperature for CPU modules mounted on a DIN 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 permitted and restricted
installation positions. Mounting must provide a clearance of 30 mm both above and below a
CX80xx device combination to ensure adequate ventilation of the base CPU module and
the power supply unit.
The high performance and the compact design of the CX80xx systems may result in increased heat
generation. The heat 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.
Installation positions with reduced temperature range up to 45°C
Other installation positions are permitted with a temperature range up to 45 °C.
