2 Mounting
2.2 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 side at the start of the DIN rail:
•
A central processing unit or
• A router module 705042 (or 705043)
These 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 con-
sideration: 17.5 mm + 2 × 9.5 mm = 36.5 mm.
NOTE!
Modules with a recent production date have 2 fixing knobs on the right side of the housing and on the
left have 2 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 removed to ensure electrical contact be-
tween the modules. For example, a cutter knife and a file can be used for removal.
Installation of a router module 1-port (705043)
Process:
1. Mount the router module (A) in the DIN rail from above (A1).
2. Pivot the router module (A) downward until it snaps into place (A2).
3. Position the end bracket (B) on the DIN rail and move to the right against the router module (B3).
