Safety Instructions
Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential
damage. Throughout this safety section, the caution icon ( ) is used to indicate cautions and precautions that you need to
review and follow.
Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions.
Observe and follow service markings. Do not service any product except as explained in your system documentation.
Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical
shock. Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your
trained service provider:
–
The power cable, extension cable, 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.
•
Keep your system away from radiators and heat sources. Also, do not block the cooling vents.
•
Do not spill food or liquids on your system components, and never operate the product in a wet environment. If the
system gets wet, see the appropriate section in your troubleshooting guide or contact your trained service provider.
•
Do not push any objects into the openings of your system. Doing so can cause a fire or an electric shock by
shorting out interior components.
•
Use the product only with approved equipment.
•
Allow the product to cool before removing covers or touching internal components.
•
Operate the product only from the type of external power source indicated on the electrical ratings label. If you are
not sure of the type of power source required, consult your service provider or local power company.
•
To help avoid damaging your system, 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 attached devices 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 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 an electric shock, plug the system 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 cable, use a 3-wire cable with
properly grounded plugs.
•
Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged into
the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or
power strip.
•
To help protect your system from sudden, transient increases and decreases in electrical power, use a
surge suppressor, line conditioner, or uninterruptible power supply (UPS).
