Assembly and connecting
Embedded PC 67
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.
