This is possible via certification under the standards ofleading agencies such as Germanischer Lloyd and Lloyds Register.For standard-compliant application in substation instrumentation and control,telecontrol systems, railway technology or shipbuilding certified operation, field-side power supply filter 750-624/040-001 or power supply filter 750-626/040-000are generally to be used for XTR module groups.Table 17: Filter Modules for 24 V Power SupplyItem No. Description Description750-626/040-000 Power supplyfilterSystem and field supply with filtering (24 V,0 V), i.e., fieldbus coupler/controller and buspower supply (750-613/040-000)750-624/040-001 Field-sidepower supplyfilter24 V field supply with filteringTherefore, the following power supply requirements must be observed:Figure 21: Power Supply ConceptThe 24 V system power supply for the fieldbus coupler/controller must be filteredand protected against overvoltage. Therefore, the power must be supplied viapower supply filter 750-626/040-000.
