Length
If you use many extension modules the controller's length will
grow accordingly. The row of modules is a complete unit which
cannot be broken.
The module dimension is 72 mm.
Modules in the 100-series consist of one module
Modules in the 200-series consist of two modules
The controller consist of three modules
The length of an aggregate unit = n x 72 + 8

Linking of modules
Start with the controller module and then mount the selected
extension modules. The sequence is of no importance.
However, you must not change the sequence, i.e. rearrange the
modules, after you have made the setup where the controller
is told which connections are found on which modules and on
which terminals.
The modules are attached to one another and kept together by a
connection which at the same time transmits the supply voltage
and the internal data communication to the next module.
Mounting and removal must always be performed when there is
no voltage.
The protective cap mounted on the controller's plug connection
must be moved to the last vacant plug connection so that the
plug will be protected against short-circuit and dirt.
When the regulation has started the controller will all the time
check whether there is connection to the connected modules. This
status can be followed by the light-emitting diode.
When the two catches for the DIN rail mounting are in open
position the module can be pushed into place on the DIN rail – no
matter where in the row the module is found.
Removal is likewise carried out with the two catches in the open
position.
