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 components. Only experienced
electronics personnel should open the chassis.
Caution! Always ground yourself to remove any static electric charge before
touching ECU-1251 Series. 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 protection
device in the power supply input port.
