fulfill local regulations. See Step 2 below for more information on how the cable shield should be
grounded.

2. Connect the wiring pair and ground as indicated in Figure 7.
a. The cable shield should:
Be trimmed close and insulated from touching the transmitter housing.
Continuously connect to the termination point.
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.
