Wiring the Power Connector

If using a different external power supply from the one provided with the SW2/SW4, you may need to wire the connector for it.

To wire the power connector,

1. Cut the DC output cord to the length needed.

2. Strip the jacket to expose 3/16" (5 mm) of the conductors.

CExposing more than 3/16” (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 may cause 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 2-pin captive screw plug and secure them, using an Extron Tweeker or other 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.

5. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

The figure below shows how to wire the connector.

Power connector wiring

WThe two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.

CDo not tin the stripped power supply leads before attaching the captive screw plug to them. 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.
