Cooling In the case of all fan cooled DYNACORD output stages the air flows from the front to the rear as cool fresh air tends to be available outside the rack rather than inside This way the output stage remains cooler and the resulting heat loss can be dissipated more efficiently Figure 5 5 Air supply and ventilation As a rule the output stage must be set up or mounted in such a way that the air supply at the front and the ventilation at the rear of the device are not impeded When installing in housings and racks it is important to ensure that the output stage is adequately ventilated There must be a free channel of air of at least 60 mm x 330 mm between the back of the output stage and the interior of the cabinet rack as far as the upper rack or cabinet ventilation system There must be free space of at least 100 mm above the cabinet for ventilation Because the temperature in the housing or cabinet can rise to as high as 40 C when the output stage is in operation the maximum permissible ambient temperature of the other devices in the rack cabinet must be observed DPA series output stages can be mounted in racks directly on top of one another without any clearance between them However since the amplifier housings heat up during operation it may be advisable to maintain a distance of 1 height unit 1 HU from other devices without forced cooling e g controller Caution The ventilation openings on the output stage must no
