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.

For vibration loads > 4g, observe the following installation instructions:
•
Use pan-head screws or blind rivets at least every 60 mm (12 mm pin
spacing) to secure the DIN rail.

Make the open conductor length between strain relief and wire connection
as short as possible.
