4. Wiring and Connections
The M-17 has an isolated power supply. This means that the installer may use
different grounds (if any) on the power supply input side from those on the output
side. Signal return is not electrically connected. This increases the flexibility the
installer has in the powering and monitoring the system; however, on the other
hand one has to be careful that all grounds are accounted for.
