Installation/dismounting on DIN rail

All modules in the system are intended for installation on a DIN rail according to DIN EN 60715
(35 mm × 7.5 mm × 1 mm).
The following must always be installed on the left, at the start of the DIN rail:
• A central processing unit or
• A router module
These modules connect the input/output modules to the voltage supply and the system bus.
NOTE!
To determine the required minimum width of the DIN rail, the widths of the individual modules
are to be added (see technical data of the modules in the respective data sheet or the
module-specific installation instructions).
The widths of the cover (17.5 mm) and both end brackets (each 9.5 mm) should also be
taken into consideration: 17.5 mm + 2 × 9.5 mm = 36.5 mm.
NOTE!
Modules with a recent production date have two fixing knobs on the right side of the case and
on the left two round holes (for greater torsional strength of the entire module assembly). If a
module with fixing knobs is to be inserted into an existing module assembly and the adjacent
module does not have the corresponding holes, the fixing knobs must be completely re-
moved to ensure electrical contact between the modules. For example, a cutter knife and a
file can be used for removal.
