Mounting Sequence
All system components can be snapped directly on a carrier rail in accordance
with the European standard EN 50022 (DIN 35).
The reliable positioning and connection is made using a tongue and groove
system. Due to the automatic locking, the individual components are securely
seated on the rail after installation.
Starting with the coupler/controller, the I/O modules are mounted adjacent to each
other according to the project design. Errors in the design of the node in terms of
the potential groups (connection via the power contacts) are recognized, as the I/O
modules with power contacts (male contacts) cannot be linked to I/O modules
with fewer power contacts.

Risk of injury due to sharp-edged male contacts!
The male contacts are sharp-edged. Handle the module carefully to prevent injury.

Insert I/O modules only from the proper directions!
All I/O modules feature grooves for power jumper contacts on the right side. For
some I/O modules, the grooves are closed on the top. Therefore, I/O modules
featuring a power jumper contact on the left side cannot be snapped from the top.
This mechanical coding helps to avoid configuration errors, which may destroy
the components. Therefore, insert I/O modules only from the right and from the
top.

Don't forget the bus end module!
Always plug a bus end module 750-600 onto the end of the fieldbus node! You
must always use a bus end module at all fieldbus nodes with the WAGO I/O
System 750 fieldbus couplers/controllers to guarantee proper data transfer.
