ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your embedded computer.
Wiring 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 DC source should be from a UL Listed Class 2 or Limited Power Source (LPS), external adaptor with output
rated at 12 to 48 VDC, 1.2 A minimum. If the power is properly supplied, the “Ready” LED will glow a solid green
after a 25 to 30 second delay.
Grounding the Unit
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Before
connecting any devices, run a ground wire from the ground screw to the grounding surface.
ATTENTION
This product should be mounted to a well-grounded mounting surface such as a metal panel.
SG: The Shielded Ground (sometimes called Protected
Ground) contact is the left most contact of the 3-pin
power terminal block connector when viewed from the
angle shown here. Connect the SG wire to an
appropriate grounded metal surface.
