1.3 Safety Precautions
The following messages inform how to make each connection. In most
cases,
you will simply need to connect a standard cable.
Note: 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 components. Only
experienced
electronics
personnel should open the chassis.
Note: Always ground yourself to
remove any static electric
charge
before touching UNO-3072L. Modern elec-
tronic
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.
Note: If DC voltage is
supplied by an external circuit, please
put a protection
device in the power supply input port.
