(if provided) on the power supply is set to match the power available at your
location:

• Also, be sure that attached devices are electrically rated to operate with the
power available in your location.
• Use only approved power cables. 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 electric shock, plug the system and peripheral power cables
into properly grounded electrical outlets.
• The peripheral power 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 three-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).
• Position system cables and power cables carefully; route cables so that they
cannot be stepped on or tripped over. Be sure that nothing rests on any cables.
• Do not modify power cables or plugs. Consult a licensed electrician or your
power company for site modifications.
• Always follow your local and national wiring rules.
• Move products with care; ensure that all casters and stabilizers are firmly
connected to the system. Avoid sudden stops and uneven surfaces.
