Introduction
1-10
y
You can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can
be bundled together.
y
Keep input wiring and output wiring separate.

Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
Connect the 12-48 VDC power line with UC-7420/7410’s terminal block. If the power is properly
supplied, the Ready LED will illuminate with a solid green color after 30 to 60 seconds have
passed.
Grounding UC-7420/7410
Grounding and wire routing helps limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection from the ground screw to the grounding surface prior to
connecting devices.
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface, such as a metal
panel.
SG
DC 12-48V
SG: The Shielded Ground (sometimes called Protected Ground) contact is
the left most contact of the 3-pin power terminal block connector
when viewed from the angle shown here. Connect the SG wire to an
appropriate grounded metal surface.
Connecting to the Network
Connect one end of the Ethernet cable to one of UC-7420/7410’s 10/100M Ethernet ports (8-pin
RJ45) and the other end of the cable to the Ethernet network. If the cable is properly connected,
UC-7420/7410 will indicate a valid connection to the Ethernet in the following ways:
