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.
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.
Voltage-selection switch
Some computers are equipped with a voltage-selection switch located near the
power-cord connection point on the computer. If your computer has a
voltage-selection switch, ensure that you set the switch to match the voltage
available at your electrical outlet. Setting the voltage-selection switch incorrectly
can cause permanent damage to the computer.
If your computer does not have a voltage-selection switch, your computer is
designed to operate only at the voltage provided in the country or region where
the computer was originally purchased.
If you relocate your computer to another country, be aware of the following:
v If your computer does not have a voltage-selection switch, do not connect the
computer to an electrical outlet until you have verified that the voltage provided
is the same as it was in the country or region where the computer was originally
purchased.
v If your computer has a voltage selection switch, do not connect the computer to
an electrical outlet until you have verified that the voltage-selection switch is set
to match the voltage provided in that country or region.
If you are not sure of the voltage provided at your electrical outlet, contact your
local electric company or refer to official Web sites or other literature for travelers
to the country or region where you are located.
