Power cords and power adapters
Use only the power cords and power adapters supplied by the
Never wrap a power cord around the power adapter or other object.
Doing so can stress the cord in ways that can cause the cord to fray,
crack or crimp. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped
over, or pinched by objects.
Protect the cord and power adapters from liquids. For instance, do
not leave your cord or power adapter near sinks, tubs, toilets, or on
floors that are cleaned with liquid cleansers. Liquids can cause a short
circuit, particularly if the cord or power adapter has been stressed by
misuse. Liquids can also cause gradual corrosion of the power cord
terminals and/or the connector terminals on the adapter which can
eventually result in overheating.
Always connect power cords and signal cables in the correct order
and ensure that all power cord connectors are securely and
completely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input
pins and/or shows signs of overheating (such as deformed plastic) at
the ac input or anywhere on the power adapter.
Do not use any power cords where the electrical contacts on either
end show signs of corrosion or overheating or where the power cord
appears to have been damaged in any way.
