IA260 Hardware User’s Manual Hardware Connection Description
Wiring Requirements
In this section, we describe how to connect various devices to the embedded computer. You
should heed the following common safety precautions before proceeding with the installation of
any electronic device:
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 When necessary, it is strongly advised that you label wiring to all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before doing installations and/or wiring.
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 ratings, the wiring could overheat, causing serious
damage to your equipment.
Temperature Caution!
Be 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
The IA260 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 sources. If
the power is properly supplied, the Power LED will light up.
The Ready LED will glow a solid
green color when the operating system is ready (it may take 30 to 60 seconds for the operating
system to boot up).
