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 WLSE, 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.
•Observe power strip ratings. Make sure that the total ampere rating of all
products plugged into the power strip does not exceed 80% of the rating.
•To help protect your system/components from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or
uninterruptable power supply (UPS).
•Do not modify power cables or plugs. Consult a licensed electri cian or your
power company for site modifications. Always follow your local/national
wiring rules.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent
static damage, discharge static electricity from your body before you touch any of
your computer’s electronic components, such as the microprocessor. You can do
so by touching an unpainted metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an u npainted
metal surface to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
•When unpacking a static-sensitive component from its shipping carton, do not
remove the component from the antistatic packing material until you are
ready to install the component in your computer. Just before unwrapping the
antistatic packaging, be sure to discharge static electricity f rom your body.
•When transporting a sensitive component, first place it in an antistatic
container or packaging.
•Handle all sensitive components in a static-safe area. If possible, use
antistatic floor pads and workbench pads.
