CONNECTIONS AND HARDWARE

FIGURE A-2. Rosemount 275 Rear Connection Panel with Optional NiCad Recharger Pack.

The HART Communicator can interface with a transmitter from the control room, the instrument site, or any wiring termination point in the loop through the communicator connections as shown in Figure A-2and Figure A-3.To communicate, connect the HART Communicator in parallel with the instrument or load resistor. The connections are non-polarized. Before connecting the HART Communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or nonincendive field wiring practices.

NOTE

The HART Communicator needs a minimum of 250 ohms resistance in the loop to function properly. The HART Communicator is not a measurement device and does not need to be calibrated; it is a communications device through which you can read and adjust the transmitter configuration information. All variable outputs displayed by the communicator are functions of the transmitter.
