The wiring procedure is the same for the sensor and transmitter. Refer to
the hazard statements on page 21 and the wiring diagrams below and
on page 23, and follow these steps:
1. Insert the stripped ends of the individual wires into the terminal
blocks. No bare wires should remain exposed.
• At the sensor, connect wiring inside the sensor junction box.
• At the transmitter, connect wiring to the transmitter's intrinsically
safe terminals for sensor wiring, as numbered in
Table 4-1
.
Transmitter terminal blocks can be unplugged for easier connection
of wiring.
2. Locate the wires by color as indicated in
Table 4-1
.
3. Tighten the screws to hold the wires in place.
4. Tightly close the sensor junction-box cover and transmitter housing.
On an ELITE sensor junction box, tighten all four cover screws.
