Power Cords And Power Adapters; Extension Cords And Related Devices; Plugs And Outlets - IBM ThinkCentre 8131 User Manual

Power cords and power adapters

Use only the power cords and power adapters supplied by the product
manufacturer.
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.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer
to obtain a replacement.
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.
