PRELIMINARY

Wiring the Power Connector

If using a different external power supply from the one provided with the SW USB,

you may need to wire the connector for it.

To wire the power connector,

. Cut the power supply’s DC output cord to the length needed.

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

Exposing more than 3/16 inch (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.

Exposing less than the recommended amount may cause the wires to slide

out of the connector too easily, even if they are tightly pinched by the

captive screws.

. Slide the exposed leads into a two-pin captive screw plug and secure them by

tightening the screws, using a small screwdriver.

. 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.

. 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 power connector.

Power connector wiring

The two power cord wires must be kept separate while the power supply is

plugged in. Remove power before wiring.

Do not tin the stripped power supply leads before attaching the captive

screw plug to them. Tinned wires are not secure in the captive screw

connectors and can be easily pulled out. They may also break after being

bent several times.
