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.
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.
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.
