UC-8410 Hardware User’s Manual Hardware Connection Description
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your UC-8410.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
Temperature Caution!
Be careful when handling the UC-8410. When plugged in, the UC-8410’s internal components
generate heat, and the outer casing may feel hot to the touch.
You should also observe the following common wiring rules:
y Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit.
To avoid interference, wires with different signal characteristics should be routed separately.
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.
y Where necessary, we strongly recommend that you label wiring to all devices in the system.
Connecting the Power
The UC-8410 has a 3-pin terminal block for a 12 to 48 VDC power input.
The following figures show how the power input interface connects to external power source. If
the power is properly supplied, t the Ready LED will illuminate with a solid green color after 30
to 60 seconds have passed.
ATTENTION
The power for this product is intended to be supplied by a Listed Power Supply Unit that is rated
to deliver 12 to 48 VDC at a minimum of 1280 mA for 12 VDC, and 300 mA for 48 VDC.
