CAUTION
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.
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
Alternatively, an Extron P/S 100 Universal 12 VDC Power
Supply can power up to ten MDAs or other Extron 12 VDC
devices using only one AC power connector.
