Connecting 5.3 Wiring setups for hazardous area installation SITRANS LR250 (FOUNDATION FIELDBUS) Operating Instructions, 08/2014, A5E32221411-AC 49 Entity concept: The Entity Concept allows interconnection of intrinsically safe apparatus to associated apparatus not specifically examined in such combination. The criteria for interconnection is that the voltage and current which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal to or greater than the output voltage (Uo) and output current (Io) levels which can be delivered by the associated apparatus, considering faults and applicable factors. In addition, the maximum unprotected capacitance (Ci) and Inductance (Li) of the intrinsically safe apparatus, including interconnecting wiring, must be equal to or less than the capacitance and inductance which can be safely connected to associated apparatus. Under the entity evaluation concept, SITRANS LR250 has the following characteristics: (input voltage) Ui = 24 V (input current) Ii = 250 mA (input power) Pi = 1.2 W (internal capacitance) Ci = 0 (internal inductance) Li = 0
Connecting 5.3 Wiring setups for hazardous area installation SITRANS LR250 (FOUNDATION FIELDBUS) 50 Operating Instructions, 08/2014, A5E32221411-AC FISCO Concept Note For complete details and instructions regarding the FISCO Concept The FM/CSA connection drawing number A5E02358161 can be downloaded from our website at: Product page (http://www.siemens.com/LR250) Go to Support > Installation Drawings > Level Measurement > SITRANS LR250. The FISCO Concept allows interconnection of intrinsically safe apparatus to associated apparatus not specifically examined in such combination. The criteria for interconnection is that the voltage (Ui or Vmax), the current (Ii, or Imax) and the power (Pi, or Pmax) which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal to or greater than the voltage (Uo or Voc or Vi), the current (lo or Isc or li), and the power (Po or Pmax) levels which can be delivered by the associated apparatus, considering faults and applicable factors. In addition, the maximum unprotected capacitance (Ci) and inductance (Li) of each apparatus (other than the termination) connected to the fieldbus must be less than or equal to 5 nF and 10 μH respectively. In each segment only one active device, normally the associated apparatus, is allowed to provide the necessary energy for the fieldbus system. The allowed voltage Uo (or Voc or Vt) of the associated apparatus is limited to the range of 14V dc to 24V dc. All other equipment connected to the bus cable has to be passive, meaning that they are not allowed to provide energy to the system, except for a leakage current of 50 μA for each connected device. Separately powered equipment needs a galvanic isolation to assure that the Intrinsically Safe fieldbus circuit remains passive. Under the FISCO evaluation concept, SITRANS LR250 has the following characteristics: (input voltage) Ui = 17.5 V (input current) Ii = 380 mA (input power) Pi = 5.32 W (internal capacitance) Ci = 0 (internal inductance) Li = 0
