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
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 ven-
tilation holes. The images show the permitted and two incorrect installation positions. Mounting must pro-
vide a clearance of 30 mm both above and below a CX50x0 device combination to ensure adequate venti-
lation 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.
