‡
To help avoid damaging your computer, be sure the voltage selection switch on
the power supply is set to match the AC 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 Japan, South Korea, and Taiwan
— 230 V/50 Hz in most of Europe, the Middle East, and the Far East
Also be sure your monitor and attached devices are electrically rated to operate
with the AC power available in your location.
‡
To help prevent electric shock, plug the computer and device power cables into
properly grounded power sources. These cables are equipped with 3-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.
‡
To help avoid possible damage to the system board, wait 5 seconds after turning
off the system before disconnecting a device from the computer.
‡
To help protect your computer system from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or un-
interruptible power supply (UPS).
‡
Be sure nothing rests on your computer system’s cables and that the cables are
not located where they can be stepped on or tripped over.
‡
Do not spill food or liquids on your computer. If the computer gets wet, consult
“If Your Computer Gets Wet” in Chapter 6.
