To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions.

General Precautions

Observe the following general precautions for using and working with your system:

l 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

l 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.

l Keep your system components away from radiators and heat sources. Also, do not block cooling vents.

l 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 chapter in your troubleshooting guide or contact a Dell-authorized service provider.

l 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.

l Use the product only with Dell products or other Dell-approved equipment.

l Allow the product to cool before removing covers or touching internal components.

l 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.

l 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.

l 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.

l 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.

l 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.

l Do not use appliance/voltage converters or kits sold for appliances with your Dell product.

l To help protect your system components from sudden, transient increases and decreases in electrical power, use a surge suppressor, line

conditioner, or uninterruptible power supply (UPS).
