BECKHOFF CX1100-000x - Manual (Page 46)

Fitting and wiring
44 Embedded PC
Mechanical assembly of the basic module
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.
Engaging on the DIN 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 DIN rail. This can be done using an ordinary screwdriver
and a slight turn.
Then fix the CX1020 block on the DIN rail using the latching straps. You should hear a soft click.
