To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment,
observe the following precautions.
Observe the following general precautions for using and working with your system:
Observe and follow service markings. Do not service any Dell product except as
explained in your Dell system documentation. Opening or removing covers that
are marked with the triangular symbol with a lightning bolt may expose you to
electrical shock. Components inside these compartments should be serviced
only by a Dell authorized service technician.
If any of the following conditions occur, unplug the product from the electrical
outlet and replace the part or contact your Dell authorized service provider:
—The power cable, extension cord, or plug is damaged.
—An object has fallen into the product.
—The product has been exposed to water.
—The product has been dropped or damaged.
—The product does not operate correctly when you follow the operating
instructions.
vii
Keep your system components away from radiators and heat sources. Also, do
not block cooling vents.
Do not spill food or liquids on your system components, and never operate the
product in a wet environment. If the computer gets wet, see the appropriate chap-
ter in your troubleshooting guide or contact a Dell-authorized service provider.
Do not push any objects into the openings of your system components. Doing so
can cause fire or electric shock by shorting out interior components.
Use the product only with Dell products or other Dell-approved equipment.
Allow the product to cool before removing covers or touching internal
components.
Use the correct external power source. Operate the product only from the type
of power source indicated on the electrical ratings label. If you are not sure of the
type of power source required, consult your Dell service provider or local power
company.
To help avoid damaging your system components, be sure the voltage selection
switch (if provided) on the power supply is set to match the power available at
your location:
—115 volts (V)/60 hertz (Hz) in most of North and South America and some Far
Eastern countries such as South Korea and Taiwan
—100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
—230 V/50 Hz in most of Europe, the Middle East, and the Far East
Also be sure that your monitor and attached peripherals are electrically rated to
operate with the power available in your location.
Use only approved power cable(s). If you have not been provided with a power
cable for your computer or storage system or for any AC-powered option
intended for your system, purchase a power cable that is approved for use in your
country. The power cable must be rated for the product and for the voltage and
current marked on the product’s electrical ratings label. The voltage and current
rating of the cable should be greater than the ratings marked on the product.
To help prevent electric shock, plug the system components and peripheral
power cables into properly grounded electrical outlets. These cables are
equipped with three-prong plugs to help ensure proper grounding. Do not use
adapter plugs or remove the grounding prong from a cable. If you must use an
extension cord, use a three-wire cord with properly grounded plugs.
Observe extension cord and power strip ratings. Make sure that the total ampere
rating of all products plugged into the extension cord or power strip does not
exceed 80 percent of the extension cord or power strip ampere ratings limit.
Do not use appliance/voltage converters or kits sold for appliances with your Dell
product.
To help protect your system components from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or un-
interruptible power supply (UPS).
