BECKHOFF CX9000 - Manual (Page 40)

Assembly and connecting
38 Embedded PC
2 Assembly of the CPU basic module with UPS module
2.1 Assembly the the CX9000 system block
In order to be able to connect the UPS to the basic CX9000 module, the cover of the basic module has to be
removed first. This is achieved by applying slight pressure on the cover. 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. If the modules are assembled the cover
can be replaced.
2.2 Engaging on the top-hat rail
Before engaging the system back on the top-hat rail the user should ensure all white tension straps are pulled down.
The user should take care of the space between the terminals and the Embedded PC system. The space for the
removed terminal must be kept to reinstall the terminal.
Then fix the CX9000 block on the top hat-rail using the latching straps. You should hear a soft click.
