Installation on the mounting rail
Snapping onto the mounting rail
The CX50x0 can simply be snapped onto the mounting rail. To this end position the block on the mounting rail and push it slightly until it engages on the right-hand side. The is indicated by a distinct click. Use a screwdriver to push up the lock on the left-hand side, thereby turning it and causing it to engage audibly.

Avoid damage! Do not force the module or apply excessive pressure! |
Installation position
Notice | |
Comply with the permitted installation position and minimum distances! 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 permitted and two incorrect installation positions. Mounting must provide a clearance of 30 mm both above and below a CX50x0 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 CX50x0 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.
Incorrect installation positions
The CX50x0 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.
