Perform work on devices only if they are de-energized!
Working on energized devices can damage them. Therefore, turn off the power
supply before working on the devices.
5.1 Mounting Sequence
Fieldbus couplers/controllers and I/O modules of the WAGO-I/O-SYSTEM
750/753 are 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 devices are securely seated
on the rail after installation.
Starting with the fieldbus 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 (blade contacts) cannot be
linked to I/O modules with fewer power contacts.
Risk of injury due to sharp-edged blade contacts!
The blade contacts are sharp-edged. Handle the I/O module carefully to prevent
injury.
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/OSYSTEM 750 fieldbus couplers/controllers to guarantee proper data transfer.
