Installation
Ventilation The HD-MD8X1/2 should be used in a well-ventilated area. The venting holes
should not be obstructed under any circumstances.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consider using
forced air ventilation and/or incrementing the spacing between units to reduce
overheating. Contact with thermal insulating materials should be avoided on all sides
of the unit.
Rack Mounting The HD-MD8X1/2 can be mounted in a rack or stacked with other equipment. Two
“ears” are provided with the HD-MD8X1/2 for rack mounting. These ears must be
installed prior to mounting. Complete the following procedure to attach the ears to
the unit. The only tool required is a #2 Phillips screwdriver.
WARNING: To prevent bodily injury when mounting or servicing this unit in a
rack, observe the following guidelines:

When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE: Observe the following guidelines when installing equipment in a rack:

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 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 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.

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).
NOTE: If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
