Mounting

6.1

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

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/O-

SYSTEM 750 fieldbus couplers/controllers to guarantee proper data transfer.
