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
expe-
rienced electronics
personnel should open the chassis.
Note: Always ground yourself to
remove any static electric charge
before touching UNO-3072L. Modern electronic devices are very sensi-
tive 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 pro-
tection
device in the power supply input port.
