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.
Be sure that the power outlet you are using is properly wired, easily accessible, and located close to
the equipment. Do not fully extend power cords in a way that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the product you are
installing.
Carefully connect and disconnect the equipment from the electrical outlet.
