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.
To prevent possible overheating, do not cover the power adapter with
clothing or other objects when the power adapter is plugged into an
electrical outlet.

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

DANGER
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.
Do not bend or modify the plug. If the plug is damaged, contact the
manufacturer to obtain a replacement.
Do not share an electrical outlet with other home or commercial
appliances that draw large amounts of electricity; otherwise, unstable
voltage might damage your computer, data, or attached devices.
Some products are equipped with a three-pronged plug. This plug fits
only into a grounded electrical outlet. This is a safety feature. Do not
defeat this safety feature by trying to insert it into a non-grounded outlet.
If you cannot insert the plug into the outlet, contact an electrician for an
approved outlet adapter or to replace the outlet with one that enables this
safety feature. Never overload an electrical outlet. The overall system load
should not exceed 80 percent of the branch circuit rating. Consult an
electrician for more information if you have questions about power loads
and branch circuit ratings.
