2.2.1 Safety notes
ESD (Electrostatic Discharge)
The modules are equipped with electronic components which may be destroyed by electrostatic discharge. When handling the modules, ensure that the environment (persons, workplace and packing) is well grounded. Avoid touching conductive components, i.e. gold contacts.
Attention
Switch off the system prior to working on bus modules!
2.2.2 Mechanical Installation
All system components can be snapped directly on a carrier rail in accordance with the European standard EN 50022 (DIN 35).
Attention
Ensure that the carrier rail is fastened with countersunk head screws or blind rivets as the snap-on foot of the I/O components extends onto the carrier rail.
The installation is simple and space saving. All modules have the same shape to minimize the project commitment.
The reliable positioning and connection of the coupler and the individual I/O modules is made using a tongue and groove system. Due to the automatic locking, the individual components are securely seated on the rail after installing.

6• WAGO-I/O-SYSTEM 750 Installation
To secure the coupler/controller against moving sideways, fix it with the orange colored locking disc on the carrier rail. To fix, insert a screwdriver into the top groove of the locking disc and press.
To pull out the fieldbus coupler, release the locking disc by pressing on the bottom groove with a screwdriver and then pulling the orange colored unlocking lug.

Installation
Self-cleaning power jumper contacts conduct the supply voltage for the field side. They are located on either side of the modules. The female contacts on the right-hand side of the fieldbus coupler and the bus modules are designed as spring contacts to protect against accidental contact. Male contacts are located on the left-hand side of the bus modules.

Danger
The power contacts have sharp-edges. Handle the module carefully to prevent injury.
Attention
Please take into consideration that some bus modules have no or only some power jumper contacts. The design of some modules does not physically allow for assembly in rows as the grooves for the male contacts are closed at the top.
The data contacts are designed as self-cleaning gold spring contacts which automatically produce a secure connection.

Warning
Do not connect the I/O module to gold spring contacts in order to avoid tarnishing or scratches!
