Configuration and Installation
5. Installation
Note: It is important in all installations that
the amplifier mains supply switch is easily
accessible.
5.1 Rack Mounting
The Procella DA4280 amplifier is shipped with
rack mount ‘ears’ attached as illustrated in
Diagram 2a
and is primarily intended to be
installed in an equipment rack. The installation
and equipment rack should be configured to
provide appropriate ventilation airflow space
around the sides and rear of the amplifier as
illustrated in
Diagram 1.
Ventilation airflow space
of at least 25 mm (1 in) should be maintained
along at least one side of the amplifier at all
times. Ventilation apertures are also located
on the rear panel of the amplifier and must
not be obstructed. It is important to retain
at least 80 mm (3.1 in) free space for airflow
behind the amplifier rear panel.
In addition to rack mount ears, optional rack
mount rear support hardware is available
and can be attached to the amplifier. Rear
support hardware may be appropriate
if the amplifier is to be used in a mobile
rack or potentially be subject to significant
movement.

rack mount rear support hardware.
