Power — 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.
N
The power connector on the rear panel is orange; however,
the plug for the power cord may be either orange or
blue. Either color plug can be connected to the rear panel
receptacle.
To wire the connector, do the following:
1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16" (5 mm) of the conductors.
W
Exposing more than the amount of copper wire
described above 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.
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 a 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.
The following fi gure shows how to wire the connector.
