5.4 Connecting IO-Link I/O modules to functional ground
5.4.1

Mounting IO-Link I/O modules on a conductive surface

Requirement
Conductive surface for mounting of the module
Required tool
To connect to functional ground, you need the following tool:
• Screwdriver or hexagon socket size 3
Required accessories:
To connect to functional ground, you need the following accessories:
• 2 x M4 fastening screws
Mounting
To connect the IO-Link I/O modules to functional ground in the case of a conductive
mounting surface, proceed as follows:
1. Drill two fastening holes. The dimensions of the module can be found in the section
Dimension drawings (Page 63).
2. Screw the module with the M4 fastening screws using a torque of 1.2 Nm.
Note
Grounding in the case of a conductive mounting surface
When you mount an IO-Link I/O module on a conductive, grounded surface, the lower
fastening screw establishes a conductive connection to the ground potential.
Ensure that there is a low-impedance connection between the module and conductive
surface as well as between the conductive surface and functional ground.

You will find more information on installing the modules in the section Mounting modules
(Page 19).
