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
