Figure 4-5. Wiring diagram for non-intrinsically safe installations (HART).

With non-intrinsically safe power supply in non-hazardous installations or Explosion-proof/Flameproof installations, wire the transmitter as shown in Figure 4-5.

NOTE!

Make sure that the power supply is off when connecting the transmitter.

Load Resistance

250 Ω

For HART communication a minimum load resistance of 250 Ω within the loop is required. For maximum load resistance. See Figure 4-1(Explosion/Flameproof) and Figure 4-2(Non-hazardous installations).

For Explosion-proof/Flameproof applications the resistance between the negative terminal on the transmitter and the power supply must not exceed 435 Ohm.

NOTE!

For Explosion-proof/Flameproof installations, make sure the transmitter is grounded to the internal ground terminal inside the terminal compartment in accordance with national and local electrical codes.
