The framework or thehousing must be grounded. The electronic connection is established via thescrew. Thus, the carrier rail is grounded.AttentionCare must be taken to ensure the flawless electrical connection between thecarrier rail and the frame or housing in order to guarantee sufficientgrounding.2.8.1.2 Insulated AssemblyInsulated assembly has been achieved when there is constructively no directconduction connection between the cabinet frame or machine parts and thecarrier rail. Here the earth must be set up via an electrical conductor.The connected grounding conductor should have a cross section of at least4 mm2 .RecommendationThe optimal insulated setup is a metallic assembly plate with groundingconnection with an electrical conductive link with the carrier rail.The separate grounding of the carrier rail can be easily set up with the aid ofthe WAGO ground wire terminals.Article No. Description283-609 Single-conductor ground (earth) terminal block make an automaticcontact to the carrier rail; conductor cross section: 0.2 -16 mm2Note: Also order the end and intermediate plate (283-320)
