Lenovo ThinkStation D20, Safety And Warranty Manual

Page: 8 / 272

• Limit your movement. Movement can cause static electricity to build up
around you.
• Always handle components carefully. Handle adapters, memory modules, and
other circuit boards by the edges. Never touch exposed circuitry.
• Prevent others from touching components.
• When you install a static-sensitive option or CRU, touch the static-protective
package containing the part to a metal expansion-slot cover or other unpainted
metal surface on the computer for at least two seconds. This reduces static
electricity in the package and your body.
• When possible, remove the static-sensitive part from the static-protective
packaging and install the part without setting it down. When this is not
possible, place the static-protective packaging on a smooth, level surface
and place the part on it.
• Do not place the part on the computer cover or other metal surface.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product
manufacturer.
The power cords shall be safety approved. For Germany, it shall be H05VV-F,
3G, 0.75 mm
2 , or better. For other countries, the suitable types shall be used
accordingly.
Never wrap a power cord around a 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 power cord 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.
