The Power LED will blink on and off for the first 5 seconds, and then maintain a steady glow once the system
has rebooted.

We recommend that you only use this function if the softw are is not work ing prop e rly and you want to load

Wiring Requirements

In this section, we describe how to connect various de vices to the embe dded computer. You must pay attention
to the following common safety precautions, before proceeding with the installation of any electronic device:

• Use separate paths to route wiring for power and devices. If power wir ing and devic e wir ing p aths must
cross, make sure the wires are perpendicular at the inters ectio n po int.
NOTE: Do not run the wires for signal or communication and power wiring in the same wire conduit. To
avoid interference, wires with diffe rent signal characteristics should b e route d 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.

• We strongly advise that you label wiring to all devices in the system for easy identification.
