Wiring Requirements

The following common safety precautions should be observed before installing any electronic device:

• Power wires and communication/signal wires should be routed through separate paths. If power and

communication/signal wires must cross paths, 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.

• Use the type of signal transmitted through a wire to determine which wires should be bundled together and

which kept separate. The rule of thumb is that wiring that carries similar electrical signals can be bundled

together.

• When necessary, we strongly advise labeling the wiring for all devices in the system.

ATTENTION

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.

ATTENTION

Safety First!

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

your device.

Electrical Current 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 rating, the wiring could overheat, causing serious damage to your

equipment.

Temperature

Caution!

careful when handling the unit. When the unit is plugged in, the internal components generate heat, and

consequently the

outer casing may feel hot to the touch.

Connecting the Power

To power on the DA-820 embedded computer, connect the power line to the DA-820’s power connector

(located on the right side of the rear panel) using the power cord shipped with the product, and then turn on

the power switch. If the power is properly supplied, the Power LED will light up first, and then the Storage LED

will start blinking when the Flash Disk Module is accessed during boot up. It takes about 30 to 60 seconds for

the operating system to boot up.
