2. Connections between foundation earthers/functional equipotential bonding cables and the reinforcement, or between functional equipotential bonding cables and the ring earther, and with the connection lugs, can take the form bolted joints, clamped joints or welded joints. Only tested connection components accordance with DIN 62561-1 (IEC 62561-1) may used.4571, is used.TBS Blitzschutz-Leitfaden 2018 / en / 2020/01/10 14:42:40 14:42:40 (LLExport_02613) / 2020/01/10 14:42:54 14:42:54 The planning aid can used to determine grid widths and versions for the foundation earthing system for individual projects.g. Detachable connections the ground must be protected against corrosion (plastic corrosion pro- tection strip). Wall penetration sealed against pressurised water DW RD10, item no. Tying wire not acceptable. recommended that stainless steel with a molybdenum content 2%, e.4571, must always be used. Alternatively, wall penetrations sealed against pressurised water (type RD10) should used.4 Versions Earthing systems can consist either type a type earther. 2360 1 Connecting parts If connections are made the earth, e.4404 1. 1.
