4.Connect the loop cable to the SIGNAL (+) and (-) terminals inside the Transmitter's enclosure. Refer to Figure 4-1, 4-2 or 4-3 for the needed connections for the type of Network. Terminals will accommodate wire sizes up to 16 AWG. Attached to both signal terminals are lugs that facilitate the connection of the MXC Communicator. DO NOT connect signal wires to the lugs.

IMPORTANT

The cable shield must be insulated from all terminals and the transmitter enclosure. Refer to Section 4.3.11 for additional shielding and grounding information.

5.Connect Sensor Wires

Hook each stripped solid wire end or insert each crimp-on terminal under the appropriate terminal screw and tighten the screw for a reliable electrical connection. Refer to figures showing the needed connections as listed below in paragraphs 1) to 4).

1)RTD Sensor - Connect the tagged RTD leads as shown in Figure 4-13 detail A, B, or C, depending upon type of RTD used.

2)Thermocouple Sensor - Connect the tagged thermocouple extension leads as shown in Figure 4-13 detail D. The positive and negative thermocouple leads are usually color coded.
