1.3 Safety Precautions
The following,messages informs how to make each connection. In most
cases, you will simply need to connect a standard cable.
Warning! Always disconnect the power cord from your
chassis whenever you are working on it. Do not
connect while the power is on. A sudden rush of
power can damage sensitive electronic compo-
nents. Only experienced electronics personnel
should open the chassis.
Caution! Always ground yourself to remove any static
electric charge before touching UNO-4672. Mod-
ern electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag.
Attention! If DC voltage is supplied by an external circuit,
please put a protection device in the power sup-
ply input port.
