a wet environment. If the system gets wet, see the appropriate section in your
troubleshooting guide or contact your trained service provider.
• Use the product only with approved equipment.
• Allow the product to cool before removing covers or touching internal components.
• 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.
NOTICE: 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.
• Be sure that your monitor and attached devices are electrically rated to operate with the
power available in your location.
• Use only power cables provided with this product.
• 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.
• Observe extension cable and power strip ratings. Make sure that the total ampere rating of
all products plugged into the power strip does not exceed 80 percent of the ampere ratings
limit for the 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/national wiring rules.
Rack Mounting of Systems
• Refer to the rack installation documentation accompanying the rack for specific caution
statements and procedures.
• System rack kits are intended to be installed in a rack by trained service technicians. If a
non-Dell rack is utilized, be sure that the rack meets the specifications of a Dell rack.
• Elevated Ambient Temperature: If installed in a closed rack assembly, the operation
temperature of the rack environment may be greater than room ambient. Use care not to
exceed the rated maximum ambient temperature of the unit.
• Reduced Air Flow: Installation of the equipment in a rack should be such that the amount
of airflow required for safe operation of the equipment is not compromised.
