Installation
The DPA output stage has been designed to be installed horizontally in a conventional 19” rack
cabinet. In general, an installation location must be selected in which the output stage is
protected from the following conditions:
•
Dripping water or spray
• Direct sunlight
• High ambient temperatures or direct effect of sources of heat
• High level of humidity
• Heavy dust accumulation
• Strong vibrations
Attaching the output stage to the front
Attach the output stage to the front using four screws and washers as shown in the following
diagram.

Notice!
Use of installation rails
When installing in rack cabinets, installation rails must always be used to prevent the front
panel becoming distorted.
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
