Do not tin the 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.

Alternately, an Extron P/S 100 Universal 12 VDC Power Supply, part #60-357-01, can power up to ten MSWs or other Extron 12 VDC devices using only one AC power connector.
