Wallplate Power Connection
The wall plate units have a 2 pin screw
terminal for power connection on the back of
the unit. You need to connect 6 vDC (could
be 6 to 9vDC) to these terminals.
In your package there is either of the 2 power
supplies pictured. There is also a 2.5 mm
Jack included in the package so that you
don’t have to cut the connector at the end of
the power supply. If you decide not to cut off
the power supply connector, then solder a
pair of wires to the enclosed jack and connect
those to the power terminals.
Using the supplied 2.5mm Jack also gives you the ability to place the power
supply outside the wall. You can use a separate single gang plate and install the
supplied jack on it and wire it to the terminals on the back of the wall units.
You can use 20 awg or heavier wire to extend the DC output cord of the power
supply if you need to locate the power supply farther from the device. It is
recommended to keep the distance of the supply from the unit to within 30 feet.
Note: Please do not connect the power supply to the AC source until you have
securely connected the output cords to the Wall Plate Mini-Cat unit.
Electrical Safety Note
Since the DC supply to the unit is only 6 to 9 vDC with minimal current
requirements, the product qualifies as a Class 2 low-voltage device, and
you are not required to run the DC cables in a conduit. However if you will
be installing the power supply in the wall or ceiling, since it has to plug in
to AC, you need an electrical junction box for it, and the AC line that
brings high-voltage to the junction-box should follow the electrical code
for your specific installation
