N
Stripping the wires to expose less than the recommended
amount causes them to slide out of the connector too easily,
even if they are tightly pinched by the captive screws.
3. Slide the leads into the supplied captive screw plug and
lock them, using an Extron Tweeker (small screwdriver).
4. Use the supplied tie-wrap to strap the power cord to the
extended tail of the connector.
5. To verify the power cord’s polarity before connecting
it, plug in the power supply with no load and check the
output with a voltmeter.
C
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 can be easily pulled out. They may
also break after being bent several times.
W
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
Alternately, an Extron PS 123 12 VDC, 3 amp power supply,
(part #60-814-01), can power up to eight MSWs or other Extron
12 VDC devices using only one AC power connector.
