WAGO I/O System 750
750-600/000-001 End Module with Potential Group
Manual
Version 1.0.1
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.

Inserting and Removing Devices
4.2.1
Inserting the End Module
1.
Position the end module at the end of the fieldbus node in such a way that
the groove and spring are connected to the preceding component.
2.
Press the end module into the assembly until the end module snaps into
the carrier rail.
Figure 5: Snap the End Module into Place
3.
Check that the end module is seated securely on the carrier rail and in the
assembly. The end module must not be inserted crooked or askew.
Once the end module has snapped into place, the electrical connection for the
data contacts to the preceding I/O module is established The end module
completes the internal data bus, while providing correct data transmission.
