CPower supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply and the product. Identify the power cord negative lead by the ridges on the side of the cord.

NThe 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.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

WThe 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.
