Itis not permitted to combine intrinsically safe and non-intrinsically safecircuits.The rated voltage of the non-intrinsically-safe circuits is:- for ATEX versions U m = 60 V- for FM versions U m = 90 V (XP, NI, DIP).• Make sure that the terminal cover over the power supplyconnection is tightly closed. With intrinsically safe output circuits,the terminal box can be opened.• For ATEX designs, use of the enclosed cable glands for theoutput circuits in accordance with the type of protection:intrinsically safe = blue; non-intrinsically safe = black.• The sensor and the transmitter housing must be connected to thepotential equalization. For intrinsically safe current outputs,equipotential bonding needs to be in place all the way along thecircuits.• Take into consideration the corrosion resistance of the meter tubematerials to the measuring medium. This is the user'sresponsibility.Note:The values indicated here are taken from the respective certificates.The specification and supplements to the respective valid approval(ATEX, FM) are decisive.Change from one to two columnsPROFIBUS DPV1 communicationOutput circuit ATEX design: intrinsically safe Ex ib IIC / IIBFM DesignIS acc. to control drawingsV14224-6 ... 1222 ..., V14224-6 ... 2222 ...,V14224-7 ... 1122 ..., V14224-7 ... 2122 ...PROFIBUS DP Uo = ± 3,72 VRS 485_IS-Interface I o P o EEx ib IIC/IIBTerminals X2, X3 [mA] [mW] C’[nF/km] L’/R’[mH/Ω]Terminal A/B ± 155 ± 144,2 ≤ 250 ≤ 28,5Min. cable cross sectionMax. input voltage U i:Max. input current I i:0,2 mm± 4,20 V± 2,66 ACi: 0 nFL i: 0 mHElectrical isolation of RS 485_IS PROFIBUS fieldbus signals A and BCable shield is connected to potential equalizationUse approved RS 485_IS interface / barriers only to disconnect intrinsically safe and non-intrinsically safePROFIBUS connections
