Power cords and power adapters

Use only the power cords and power adapters supplied by the product
manufacturer. The power cord and power adapter are intended for use with
this product only. They should never be used with any other product.
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.

Extension cords and related devices

Ensure that extension cords, surge protectors, uninterruptible power supplies,
and power strips that you use are rated to handle the electrical requirements
of the product. Never overload these devices. If power strips are used, the
load should not exceed the power strip input rating. Consult an electrician for
more information if you have questions about power loads, power
requirements, and input ratings.

Plugs and outlets

If a receptacle (power outlet) that you intend to use with your computer
equipment appears to be damaged or corroded, do not use the outlet until it
is replaced by a qualified electrician.
