Assembly and connecting

Mechanical installation of the fieldbus connection
Installation of a fieldbus connection involves several steps:
1. Removing the cover of the basic CX1020 module
In order to be able to connect the fieldbus to the basic CX1020 module, the cover of the basic CX1000/CX1020
module has to be removed first. This is achieved by applying slight pressure on the cover.
2. Assembly and connection to the CX1000/CX1020 configuration
Since the CX1000 configuration is already positioned on the top-hat rail, the assembly first has to be pushed onto the
top-hat rail. To this end the latching mechanism has to be released by pulling the white straps downwards.
The assembly is connected to the existing CX1000/CX1020 configuration by simply plugging the two units together.
Care must be taken that the plug of the PC104 interface is not damaged.
When correctly assembled, no significant gap can be seen between the attached housings. Finally, the white straps
are returned to their original position, so that the locking mechanism engages.
