Safety Cautions
To greatly reduce the risk of physical injury, electrical shock, fire, and damage to equipment, observe the
following precautions.
Observe and follow service markings.
• Do not attempt to service any product, except when it is explained in the system’s documentation.
• Opening or removing covers, marked with a high voltage sign, may expose the user to electrical
shock.
• Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or
contact your trained service provider:
• Damage to the power cable, extension cable, or plug.
• An object has fallen into the product.
• The product has been exposed to water.
• The product has been dropped or damaged.
• The product does not operate correctly when the operating instructions are correctly followed.
General safety cautions:
• Keep the system away from radiators and heat sources. Also, do not block cooling vents.
• Do not spill food or liquids on system components, and never operate the product in a wet
environment. If the system gets wet contact your trained service provider.
• Do not push any objects into the openings of the system. Doing so can cause fire or electric shock
by shorting out interior components.
• Only use this product with approved equipment.
• Allow the product to cool before removing the cover or touching internal components.
• Operate the product only from the type of external power source indicated on the electrical ratings
label. If unsure of the type of power source required, consult your service provider or local power
company.
• Be sure that attached devices are electrically rated to operate with the power available in your
location.
• Use only approved power cable(s). 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. 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 using
an extension cable is necessary, use a 3-wire cable with properly grounded plugs.
• Observe the 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 the 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 or national wiring rules.
• DO NOT COVER THE VENTILATION HOLES on the enclosure to protect the equipment from
over-heating.
