STEP 5. CONNECTING THE WIRES
Using the wire labels as a guide, insert each labelled wire into
its matching connector block. Insert only one wire in each
connector.
When installed correctly, the release lever of the terminal block
will lower to indicate a complete connection. Gently tug on the
wire to ensure it's fully connected.
When all the wires are connected, gently push any excess wire
back into the wall.
