MSW 4V & 4SV, cont’d
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.
