Mounting Sequence
Fieldbus couplers, controllers and I/O modules of the WAGO I/O System 750 are
snapped directly on a carrier rail in accordance with the European standard EN
60175 (DIN 35).
The reliable positioning and connection is made using a tongue and groove
system. Due to the automatic locking, the individual devices are securely seated
on the rail after installation.
Starting with the fieldbus coupler or 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 (blade contacts) cannot be
linked to I/O modules with fewer power contacts.
Insert I/O modules only from the proper direction!
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 I/O modules. 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 WAGO I/O System
750 fieldbus couplers or controllers to guarantee proper data transfer.
