Once that the bottom rear plastic box of the
system is arranged in the wall, take the front
panel with the electronic board, insert the
two transparent plastic pins present on frame
into the appropriate holes on the wall box
and get ready to connect the wires to the
terminal blocks. Make sure that all cables,
including LAN, have not yet been powered
before connecting them to the card. These

connecting. Remove, connect, and replace
the terminals according to the connections to
be made. To make the connections do not
remove the system board from the front
panel but just remove the insertion
connectors.
