10. Connect the core processor housing internal ground screw if earth ground is required.
Earth ground is required if the core processor cannot be grounded via sensor piping,
and local codes require internal ground connections.
Do not connect shield drain wires to this terminal.
11. Reinstall and tighten the core processor lid.
12. To connect the cable to the transmitter, connect the four wires from the core
processor to the appropriate terminals on the transmitter.
