Intrinsically Safe Entity Parameters: Vmax = 10.03Vdc, Imax = 592mAdc, Ci = 0.3uF, Li = 0mH.B. Selected Barriers must be galvanically isolated or dual channel shunt zener diode barriers with linear outputs, used channel to channel and having entity parameterssuch that Voc < Vmax, Isc < Imax, Ca > Ci + Ccable, La > Li + Lcable.C. For Ccable and Lcable, if the capacitance per foot or the inductance per foot is not known, then the following values shall be used:Ccable = 60pF/foot and Lcable = 0.2uH/foot.D. Selected Barriers must be installed in accordance with the barrier manufacturer's control drawing and Article 504 of the National Electrical Code ANSI/NFPA 70.E. The XTR-Series sensor element does not provide 500V isolation with respect to earth.Notes for installation in Europe:Sensor: Xentaur XTR-series Dewpoint Sensor ElementEEx ia IIC T6 DEMKO Certificate No. 05 ATEX 0505798XA. Intrinsically safe circuit parameters: Ui : 10.03Vdc, Ii : 592mAdc, Ci : 0.3uF, Li : 0mH.B. Selected Barriers must be galvanically isolated or dual channel shunt zener diode barriers with linear outputs used channel to channel and having entity parameterssuch that Uo < Ui, Io < Ii, Co > Ci + Ccable, Lo > Li + Lcable.C. For Ccable and Lcable, if the capacitance per foot or the inductance per foot is not known, then the following values shall be used:Ccable = 200pF/meter and Lcable = 0.66uH/meter.D. The wiring of the intrinsically safe circuit may be installed in accordance with EN60079-14 oraccording to national installation requirements.E. The XTR-Series sensor element does not provide 500V isolation with respect to earth andthe leakage current is higher than 5mA. The sensor shall be connected to PE earth orinstalled such that it will satisfy a 500V dielectric with respect to earth.TOLERANCES:(unless otherwise stated)Decimal.X = – .030 .XX = – .010 .XXX = – .005Angular – 1 deg.Do Not Scale Drawing.XENTAUR Corporation3661 HORSEBLOCK RD.
