Grounding
3.7.1
Grounding the DIN Rail
3.7.1.1
Framework Assembly
When setting up the framework, the carrier rail must be screwed together with the
electrically conducting cabinet or housing frame. The framework or the housing
must be grounded. The electronic connection is established via the screw. Thus,
the carrier rail is grounded.
DANGER
Ensure sufficient grounding is provided!
You must take care to ensure the flawless electrical connection between the
carrier rail and the frame or housing in order to guarantee sufficient grounding.
3.7.1.2
Insulated Assembly
Insulated assembly has been achieved when there is constructively no direct
conduction connection between the cabinet frame or machine parts and the carrier
rail. Here the earth ground must be set up via an electrical conductor accordingly
valid national safety regulations.
Note
Recommendation
The optimal setup is a metallic assembly plate with grounding connection with an
electrical conductive link with the carrier rail.
The separate grounding of the carrier rail can be easily set up with the aid of the
WAGO ground wire terminals.
