Peel off the double-sided tape from the rubber feet and affix the rubber feet
at the locations shown in the following figure.

Rack Mounting (Important Notes on
Heat Radiation)
When you are mounting the unit on a rack or the like, give attention to the
following points to ensure efficient cooling.
• Install in a well-ventilated location.
• Avoid mounting in a sealed rack. Warm air within the rack cannot
escape and is sucked into the unit again, making efficient cooling
impossible.
• When you are using a stacked mounting arrangement, be especially sure
to provide for adequate ventilation within the rack to keep discharged
air from being sucked back into the unit. If the back surface of the rack
cannot be kept open, then provide a ventilation port or ventilation fan at
the upper area of the back surface of the rack, where warm air
accumulates.
• When you are using the unit in a portable case or rack, remove the
covers from the front and back surfaces of the case, so that the front and
back surfaces of the unit are not obstructed.
• If an error message informing you of a dangerous rise in temperature
appears (p. 132), then heat-dissipating measures are needed. Refer to the
cautions just described and check the installed state of the unit and the
rack.
* When placing the unit on the rack, be careful not to pinch your fingers.
* For more information about installation, also see “Placement” in the Important
Notes (p. 5).
