3.3 Attaching the system interface to the CX20x0 system
Opening the PCI Express bus cover
The system interfaces for the CX20x0 system are connected via the internal PCI Express bus, which has a
protective cap. The cap can be removed with a screwdriver. To this end insert the screwdriver into the recess
in the short side (see diagram) and lever off the cap. The bus connector is then accessible, as shown in the
diagram.
Once the bus connector is accessible, the module can be attached on the left-hand side.
The module audibly locks into place.
Further modules can be connected to the system in the same way. Once all modules are connected, the
system is placed on the DIN rail as a block. For details please refer to the section on DIN rail mounting.
Note
Maximum number of system interfaces
Up to four system interfaces can be attached on the left-hand side of the system.
CX2500-002010 Version: 1.0

Mounting and wiring
3.4 Installation on the mounting rail
Snapping onto the mounting rail
The CX20x0 can simply be snapped onto the mounting rail. The bar clips are inserted on the top side and
underside Then simply position the block on the mounting rail and push it slightly until it engages on the
right-hand side. This is indicated by a distinct click. The bars are then engaged again. The engagement of
the individual bars is indicated by a distinct click.
Attention
Avoid damage!
Do not force the module or apply excessive pressure!
Installation position
Attention
Comply with the permitted installation position and minimum distances!
The maximum ambient temperature for CPU modules mounted on a DIN rail is 60°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 below show the permitted and two
incorrect installation positions. Mounting must provide a clearance of 30 mm both above
and below a CX20x0 device combination to ensure adequate ventilation of the base CPU
module and the power supply unit.
Correct installation position
The high performance and the compact design of the CX20x0 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.
CX2500-0020 11Version: 1.0

Mounting and wiring
Incorrect installation positions
The CX20x0 system must not be operated vertically on the DIN 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.
CX2500-002012 Version: 1.0

Mounting and wiring
3.5 Mounting the module lock
Mounting the lock
The CX20x0 controller system is fully modular, i.e. all system interfaces of the system are field-configurable.
As a rule the latching of the modules to each other is sufficiently strong. However, it is possible for the
controller and its modules to be exposed to vibrations, shocks or impacts. The modules can be securely
connected to one another with the aid of bar clips.
The bar clips are inserted on the top side and underside.
If all system interfaces are locked, then the entire assembly can be snapped onto the support rail.
Dismounting the lock
In order to dismantle the assembly it must first be removed from the support rail. Afterwards the bar clips can
be removed with the aid of a screwdriver:
CX2500-0020 13Version: 1.0

Mounting and wiring
Once the bar clips have been raised they can be pulled out. Subsequently, the system interfaces can be
separated again.

Commissioning / Configuration
4 Commissioning / Configuration
4.1 Switching on and off
Switching on
The power supply for the basic CPU module comes from the power supply unit. The basic CPU module
starts automatically when the power supply unit is connected to the mains.
Switching on for the first time
When you switch on the PC for the first time, the pre-installed operating system (optional) will be started.
Switching off
The Embedded PC switches off when the power supply unit is switched off. The control software typically
running on Embedded PCs should be shut down or stopped correctly. A user who may not close software
may also not switch the Embedded PC off, since data can be lost from the hard disk by switching off while
software is running.
Once the software has been stopped, the operating system can be shut down. Only then should the power
supply be interrupted.
