1 Power connector — Plug the external 12 VDC power supply
into this 2-pin, 3.5 mm captive screw connector. The power
supply is included with the unit.
To wire the connector:
1 . Cut the DC output cord to the length needed.
2 . Strip the jacket to expose 0.2 inches (5 mm) of the
conductors.
Exposing more than 0.2" (5 mm) of the copper
wires could allow the stripped wires to touch each
other, causing a short circuit. This could result in
the external DC power supply overheating and/or
burning.
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 . 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.
The figure on the next page shows how to wire the connector.
