Mechanical mounting of the Fieldbus modules
The mounting of the Fieldbus modules takes place in several
steps:
1. Remove cover at CX1000/CX1020 basic module
In order to be able to fasten the connection of the fieldbus connection to the CPU basic module, the cover must first
be removed (FIG 1, 2). This can be achieved by a small pressure against the cover.
FIG.1+2: Remove Cover
2. Assembly with CX1000/CX1020 configuration
Because the CX1000 configuration is already on the top-hat rail, the fieldbus module first has to be pressed on the
top-hat rail. For that purpose the locking of the latching mechanism with the white tension straps (pull down) is
required.
The attachment of the individual modules is done by simple plugging them together (FIG. 3). 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. At the end the white
tension strips must be shifted into the starting position again in order that the latching mechanism locks.
