6 Safety Instr uctions
• Use the product only with Dell products or other Dell-approved
equipment.
• Allow the product to cool before removing covers or touching internal
components.
• Use the correct external power source. Operate the product only from
the type of power source indicated on the electrical ratings label. If you
are not sure of the type of power source required, consult your Dell
service provider or local power company.
• Use only approved power cable(s). If you have not been provided with
a power cable for your server, storage system, or appliance, 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/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. 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 extension cable or power
strip ampere ratings limit.
• To help protect your system/components 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 system cables
and the power cable and plug so that they cannot be stepped on or
tripped over. Be sure that nothing rests on your system components'
cables or power cable.
• Do not modify power cables or plugs. Consult a licensed electrician or
your power company for site modifications. Always follow your
local/national wiring rules.
