44 • The WAGO-I/O-SYSTEM 750 Grounding 2.8 Grounding 2.8.1 Grounding the DIN Rail 2.8.1.1 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. Attention Care must be taken to ensure the flawless electrical connection between the carrier rail and the frame or housing in order to guarantee sufficient grounding. 2.8.1.2 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 must be set up via an electrical conductor. The connected grounding conductor should have a cross section of at least 4 mm2. Recommendation The optimal insulated 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. Item No. Description 283-609 1-conductor ground (earth) terminal block make an automatic contact to the carrier rail; conductor cross section: 0.2 -16 mm2 Note: Also order the end and intermediate plate (283-320).
