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:
lKeep the device unplugged until all of the input, network, output,
and speaker wiring is complete.
NOTES:
lEnsure that the unit is properly grounded by connecting the
chassis ground lug to an earth ground (building steel).
lTo 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).
lDo not bundle power cords together with connection cables.
Doing so can result in noise.
