Mechanical assembly of the basic module

The installation of the modules takes place in three steps:
1. The sequence of the modules
The basic CPU module with system interfaces, which are factory-installed on the left side, is extended with
the power supply unit on the right and with the fieldbus connection (master or slave) left side if available.
2. Assembly of the CPU and the power supply unit
The individual modules are simply plugged together. The PC104 connector plugs should be handled
carefully in order to avoid damage. When correctly assembled, no significant gap can be seen between the
attached housings.
3. Engaging on the top-hat rail
On the bottom of the modules, there is a white tension strap, which is connected with a latching mechanism.
These tension straps must be pulled down before attaching to the top-hat rail. This can be done using an
ordinary screwdriver and a slight turn.
Then fix the CX1020 block on the top hat-rail using the latching straps. You should hear a soft click.
Do not force the module or apply excessive pressure!
Only apply pressure at insensitive points of the housing (edges). Never apply pressure on the display, the
buttons or movable parts of the CX10x0 system.
After successful latching on the top-hat rail the straps should be pushed back to their original position.
Note:
A locking mechanism prevents the individual housings from being pulled off again. Detailed information
relating to disassembly of the CX1020 configuration from the top-hat rail can be found on page "Removal and
disposal [} 176]".
