To verify proper polarity before connection to a device,
plug in the power supply with no load and check the
output polarity with a voltmeter. Remove power before
continuing.
W
When verifying power supply polarity, the two
power cord wires must be kept separate while the
power supply is plugged in.

N
The length of the exposed (stripped) copper wires is
important. The ideal length is 3/16" (5 mm). Longer
bare wires can short together. Shorter wires are not
as secure in the captive screw connectors and could be
pulled out.
Do not tin the stripped power supply leads. Tinned
wires are not as secure in the captive screw connectors
and could be pulled out.
