Chapter 1. Important safety information
Protect power cords and power adapters from liquids. For instance, do not
leave your power 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 power cord or power adapter has been stressed by misuse.
Liquids also can cause gradual corrosion of power cord terminals and/or the
connector terminals on a power 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 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.
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.
