Wiring Requirements

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your

UC-8410/8416/8418/8430.

Wiring Caution!

Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes

dictating the maximum cu

rrent 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-8410/8416/8418/8430. When plugged in, the UC-8410/8416/8418/8430

’s

internal components generate heat, and

the outer casing may feel hot to the touch.

You should also observe the following common wiring rules:

• 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.

• 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.

• Keep input wiring and output wiring separate.

• Where necessary, we strongly recommend that you label wiring to all devices in the system.

Connecting the Power

The UC-8410/8416/8418/8430 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.

Grounding the UC-8410/8416/8418/8430

Grounding and wire routing help 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 mount

ed to a well-grounded mounting surface, such as a metal panel.
