4.1a Installation Drawing Intrinsically Safe M-Series Digital, 650838 (Revision F) Continued NOTES: 1. Safety barriers are FMRC approved and/or CSA Certified (as applicable) with entity parameters and must be used in an approved configuration where the following conditions are met: • Voc, or Vt of the barrier combination is less than Vmax of the transmitter. • Isc, or It of the barrier combination is less than Imax of the transmitter. • Ca of the barrier combination is greater than the total Ci of the transmitters plus the cable capacitance. • La of the barrier combination is greater than the total Li of the transmitters plus the cable capacitance. Total Li of the transmitters plus the cable capacitance. Transmitter entity parameters: Vmax = 28V Imax = 200mA Ci = 0 Li = 0 2. Power supply cable must be 24awg or heavier, shielded twisted pair cable. Cable capacitance must be less than 50pF per foot. Cable shield is connected to system ground at safety barrier end only. See installation manual for additional cable information. 3. Communications cable must be 24awg or heavier, shielded twisted pair cable. Cable capacitance must be less than 24pF per foot. Cable shield is connected to system ground at safety barrier end only. See installation manual for additional cable information. 4. The wire connection between earth ground and the safety barrier ground terminal must be less than 1 ohm. 5. Maximum approved number of DDA or MODBUS gauges for intrinsically safe wiring networks is 10. See operation and installation manual for system configurations and restrictions. 6. Connection to earth ground for transient protection circuitry. 7. Ground screw provided to connect gauge housing to earth ground. 8. The transducer frame shall be grounded to earth ground directly or through the equipment on which it is mounted and shall be at the same potential as the safety barrier ground electrode. 9. Electronic equipment connected to associated apparatus must not use or generate more than 250 volts RMS. 10. Cable sets that are run together must have sufficient insulation to withstand 250 volts RMS between sets. 11. All wiring must meet the requirements of the NEC or CEC Part I (whichever is applicable) and any local codes. 12. Dust tight seal at conduit entry required in Class II or Class III locations. 13
