Wiring Requirements

This section describes how to connect serial devices to the embedded computer.

You should heed the following safety precautions, and review them carefully before proceeding with the

installation of any electronic device:

• 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.

• 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.

• It is advisable to label the wiring to all devices in the system.

ATTENTION

Safety First!

Be sure to disconnect the power cord before instal

lation and/or wiring.

Watch Electrical Current

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.

Watch Temperature

Be careful when han

dling the unit. When the unit is plugged in, the

internal components generate heat, and

consequently the outer casing may feel hot to the touch.
