Grounding the UC-8100
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI).
SG:
The shielded ground (sometimes called
protected ground) contact is the top
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.
ATTENTION
The product is intended to be supplied by an UL Listed power
adapter whose output meets SELV/LPS, and is rated 12-24 VDC,
minimum 0.5 A, Tma = 85°C (minimum).
