4.3 Mounting modules

DANGER Switch off the power supply
Before performing any installation and connection activities, ensure that the power supply to
the ProLink system is switched off, including external power sources.
Earthing
Functional earth is a low impedance current path between circuits and earth that is not intended as a protective
measure but, for example, to improve interference immunity.
The modules have a FE spring (metal clamp) at the bottom of their electronic sockets, which provides an electrical
connection to the mounting rail. Connect the mounting rail to the protective earth via earth terminals. This means
that the modules are also earthed when they are snapped onto the mounting rail.
If failures occur at the sensor signals, please connect the shield of the sensors to the FE terminal of the
corresponding sensor connector on the ProLink device.
The functional earth FE is only used to discharge interference. It does not serve as
protection against accidental contact for persons.
Installation of the ProLink modules
The ProLink system is set up by connecting the individual modules. You do not need any tools.
Proceed as follows to install the modules of the ProLink device on the mounting rail:
1. Place the module slightly tilted with the top edge of the mounting rail recess on the mounting rail (A).
2. Push the module down onto the mounting rail until it clicks into place (B):
3. Attach end brackets on both sides of the ProLink system to secure the system to the mounting rail.
You can now set up and connect 17 the modules of the ProLink device.
