1. Minimum network resistance equals the sum of the barrier resistances and the current sense resistor. Minimum
value is 250 Ohms; maximum value is 1100 Ohms.
2. Connect the HART Communicator as shown in Figure 2-2 for hazardous and non-hazardous locations. The
HART Communicator is a non-polar device.
3. Supply and return barriers are shown. Interconnect all cable shields and ground only at the barriers.
4. Procidia (Model 353R or i|pac) terminal assignments are:
•
34 – Analog Input 1 +
•
35 – Analog Input 1 Common
•
33 – 24 Vdc
•
18 – Station Common
5. For access to transmitter field terminals, remove the enclosure cap.
6. Maximum cable length is as calculated using the formula in section 4.3.6.
