• Do not push any objects into the openings of your system. Doing so can cause fire or
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.
• Keep the system away from direct or excessive moisture and extremely hot or cold
temperatures to ensure that the system is used within the specified operating range.
• Leave a 10.2 cm (4 in) minimum clearance on all vented sides of the system to permit the
airflow required for proper ventilation.
• Do not restrict airflow into the system by blocking any vents or air intakes.
• Clean the air vents on the front, back, and vented sides of the system. Lint, dust and other
foreign materials can block the vents and restrict the airflow.
• Do not stack systems on top of each other or place computers so close to each other that
they are subject to each other's re-circulated or preheated air.
• Do not operate the system within a separate enclose unless adequate intake and exhaust
ventilation are provided on the enclosure that adhere to the guidelines listed above.
• 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.
your service provider or local power company.
• 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.

The voltage and current rating of the cable should be greater than the ratings marked on

• To help prevent 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.
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).
To help avoid damaging your system, be sure the voltage selection switch (if provided) on the power
supply is set for the voltage that most closely matches the AC power available in your location. Also be
sure that your monitor and attached devices are electrically rated to operate with the power available in
your location.
