C Power supply voltage polarity is critical. Incorrect
polarity can damage the power supply and the product.
Identify the power cord negative lead by the ridges on the
side of the cord.
N The length of the exposed (stripped) copper wires is
important. The ideal length is 3/16” (5 mm). Longer bare
wires can short together. Shorter wires are not as secure in
the captive screw connectors and could be pulled out.
Do not tin the stripped power supply leads. Tinned wires
are not as secure in the captive screw connectors and could
be pulled out.
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
W The two power cord wires must be kept separate while
the power supply is plugged in. Remove power before
wiring.
As an alternative, an Extron PS 123 Universal 12 VDC Power
Supply, part #60-814-01, can power multiple Extron 12 VDC
devices using only one AC power connector.
Insert the wired plug into the power connector on the rear
panel, then connect AC power.
