Remove the screws to remove the adapter board. Carefully handle the adapter board and wiring to
avoid any damage. With the power supply off, connect the (+) side of the power supply to the (+)
OUT terminal of the electronics module. Connect the (-) side of the power supply through a 250
Ω
resistor to the (-) OUT terminal of the electronics module. See Figure 7-2. Connect the input
terminals 1 and 3 in series with the current loop to be measured. Terminal 1 should be more positive
than 3.

If the optional second 4-20 mA adapter board was ordered, the terminals 1 (+), 2 (-) on the adapter
board would also be connected to the 24 V dc power supply. This will provide the snout temperature
from the RTD in the process (located next to the diaphragm). Replace the display by aligning the
holes with pins and pushing the display gently into place. At this time you are ready for set-up using
the display, or the optional SmartLink software/modem or the optional HART 275 communicator.

The IPX II is supplied with a 11.5’ (3.5 m) cable for the transmitter output. A breakdown of the wiring
schematic is displayed in Table 7-2.
