Turn O the Main Breaker
Neurio should only be installed when the main breaker in the panel is turned o .
Check the Consumer Unit
Take the cover o the Consumer Unit (CU). It should look something like this:
Take special note of where the mains wire enters and connects to the main breaker. High voltage will remain
on these terminals even when the main breaker is turned o , so caution must be taken to avoid them.
The leads on the CTs are 4ft long, and the voltage cables are 2ft long. Try to nd a location that's within 4ft of
the mains service wire and 2ft of the breakers and the neutral bus bar. Make sure there's enough room on
either side of Neurio to connect the CTs, voltage cable, and antenna cable.
Once you've found your location, drill the two self-drilling mounting screws into the panel to mount Neurio.
Connect the Voltage Cable
Plug the voltage cable to the matching connector port on Neurio.
Take the white wire and connect it to the neutral bus bar.
If an empty breaker is available, connect Neurio's black wire to it. If no breakers are available, disconnect the
wire from an occupied 15A or 20A breaker, and replace it with a jumper wire of equivalent or lower gauge.
Use the included wire tap to connect the jumper wire, Neurio's black wire, and the original wire back to this
The red and blue wires are on the voltage cable are unnecessary for a single-phase home, so use the
marette included in the Neurio package to cap them together, and leave them unused.
