Rack Mounting Safety Precautions
Elevated Operating Ambient Temperature: If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than the room ambient
temperature. Therefore, consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
Reduced Airflow: 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.
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 circuits 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-mounted 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).
Connect the Device
Make the necessary connections as called out in the following illustration. Connect power last.
CAUTION:
l
Keep the device unplugged until all of the input, network, output, and speaker wiring is
complete.
NOTES:
l
Ensure that the unit is properly grounded by connecting the chassis ground lug to an earth
ground (building steel).
l
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range of 32° to 104°F (0° to 40°C).
l
Do not bundle power cords together with connection cables. Doing so can result in noise.
