STEP 4: CONNECT WIRING AND POWER UP
Use the following steps to wire the transmitter:
1. Remove the housing cover on the FIELD TERMINALS side.
2. Connect the power leads to the terminals indicated on the terminal block label.
• Power terminals are polarity insensitive - connect positive or negative to either terminal
3. Ensure proper grounding. It is important that the instrument cable shield:
• be trimmed close and insulated from touching the transmitter housing
• be connected to the next shield if cable is routed through a junction box
• be connected to a good earth ground at the power supply end
4. Plug and seal unused conduit connections.
5. If applicable, install wiring with a drip loop. Arrange the drip loop so the bottom is lower
than the conduit connections and the transmitter housing.
6. Replace the housing cover.
