Signal Wiring Grounding
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical
equipment. Grounding terminations are provided on the outside of the sensor module and
inside the Terminal Compartment. These grounds are used when transient protect terminal
blocks are installed or to fulfill local regulations. See Step 2 below for more information on
how the cable shield should be grounded.
1. Remove the Field Terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 6. The cable shield should:
a. Be trimmed close and insulated from touching the transmitter housing.
b. Continuously connect to the termination point.
c. Be connected to a good earth ground at the power supply end.

3. Replace the housing cover. It is recommended that the cover be tightened until there is
no gap between the cover and the housing.
4. Plug and seal unused conduit connections.
