• Only use attachments and/or accessories specified by the manufacturer.

Understanding Safety Symbols

DANGER HAZARDOUS VOLTAGE
The lightning flash with the arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated dangerous voltage within the product’s enclosure that may be of sufficient magnitude to constitute a  risk of electric shock to persons.
WARNING
A warning alerts you to a situation that could result in serious personal injury or death.
CAUTION
A caution alerts you to a situation that may result in minor personal injury or damage to the product and/or property.
NOTE
A note is used to highlight procedures pertaining to the installation, operation, or maintenance of the product.
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation and maintenance of the product.
DANGER HAZARDOUS VOLTAGE
To reduce the risk of electrical shock, always unplug this device from the electrical outlet before cleaning.
WARNING
Failure to read, understand and follow the following information can result in serious personal injury, damage to the equipment or voiding of the warranty. It is the responsibility of the Installer/User to ensure that this product is loaded  according to specifications.
WARNING
Risk of Electric Shock: Connect the device to a properly grounded outlet only. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

Safety Instructions: Rack Mount
Elevated Operating Ambient: If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuit might have on overcurrent protection and supply wiring. Appropriate consideration  of equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing: Reliable earthing of rack-mounting equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
Disconnect Device (Pluggable Equipment): The socket-outlet shall be installed near the equipment and shall be easily accessible.
When using electrical products, basic precautions should always be followed, including the following:

• Read and follow all instructions before using.
• There are no user-serviceable components within this device. Removal of the cover from this device may present a shock hazard, and void the warranty.
• The mains plug is used as your disconnect device. This device shall remain readily operable.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Do not overload the wall outlet where this device is being connected. Do not overload this device. Ensure the total load to this device does not exceed that which is listed in the specifications section of this manual.
• Ensure this device is connected to a properly grounded AC power source. Ensure the device is plugged into a source providing the required 120V. Do not use a plug adapter that defeats the ground pin of the AC plug.
