CAUTION Power supply voltage polarity is extremely important. Applying power with incorrect voltage polarity could damage the power supply and the MDA. Identify the power cord negative lead by the ridges on the side of the cord.

and could be pulled out.

Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

Your MDA may have shipped with a blue captive screw connector. This blue connector can be plugged into either a blue or an orange power receptacle.

The ideal length of exposed (stripped) copper wire for the blue connector is 0.2" (5 mm).

The blue connector does not have the extended tail or the included tie-wrap.

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.

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 100 Universal 12 VDC Power Supply, part #60-357-01, can power multiple MDAs or other Extron 12 VDC devices using only one AC power connector.
