Installation on mounting rails
Snapping onto the mounting rail
The CX80xx can simply be snapped onto the mounting rail. To this end simply 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.

Permissible installation positions and minimum distances
Installation positions
Installation position up to 55 °C
Notice | |
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.
