To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
C
Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the product. If a voltmeter is not available, 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 before
installing the captive screw connector. Tinned wires are
not as secure in the captive screw connectors and could
be pulled out.
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 P/S 123 Universal 12 VDC Power
Supply, part #60-814-01, can power multiple MTPs or other
Extron 12 VDC devices using only one AC power connector.
Insert the wired plug into the power connector on the rear panel.
