You have to use a PELV orFELV power supply unit with protective grounding for a fieldbus node withoutPROFIsafe I/O modules.Avoid unacceptably high body voltages!All 230 V AC voltages applied to the nodes must also be protected by a 30 mAresidual current circuit breaker.In the simplest case, place the residual current operated circuit-breaker just behindthe junction of the supply network. Doing so allows you to fuse all paths.Avoid vagabond voltages!Never use a power supply unit to power fieldbus nodes with PROFIsafe I/Omodules and fieldbus nodes with 230 V I/O modules.7.2.2.2 230V AC I/O Modules and PROFIsafe I/O Modules are Used Togetherin one Fieldbus NodeAn isolation transformer (basic insulation) must be used to supply the voltage forthe 230 VAC I/O modules. Between adjoining 230 VAC and 24 VDC I/Omodules, you have to take into account the double basic insulation and ifnecessary, use separation modules 750-616/030-000.Pos: 37 /Dokumentation allgemein/Gliederungselemente/---Seitenwechsel--- @ 3\mod_1221108045078_0.docx @ 21810 @ @ 1
