  For more information see data sheet.
Caution: Make sure that there is equipotential bonding along the entire wiring run both inside and outside the explosion hazardous area.
  Switch off device if it is installed in zone 0 and in temperature class T5 and T6 and it fails!
Burden: - current output
2-wire circuitry:
  standard: Ra = UB-14 V / 20 mA (KOhm)
Ex-protection: Ra = UB-15 V / 20 mA (KOhm)
  - voltage output:
a current of 20 mA can be obtained in the case of devices with power output.
Burden influence: for 500 Ohm burden of change: ≤ 0.1 % f.s.
