6.2.2. Mounting front grille
The front grille is shipped on top of the amplier inside the box to protect it during shipping. The front grille adheres
to the amplier with magnets. Hold the front grille with your ngers in each of the side cutouts and slide it gently into
place straight from the front.
NOTE: Always ensure the dust lters behind the detachable front panel are clean to ensure maximum
possible airow. The exterior front panel is held in place by powerful magnets but is easy to detach by
using your ngers in the openings at the each side. To clean the foam lter, detach it from the exterior
front and gently use a vacuum cleaner or gently shake it. Remount with the opposite procedure. Never
operate the amplier without the dust lter installed.
6.3. Cooling and fan operation
D Series devices use a forced-air cooling system with airow from front to rear, allowing high continuous power
levels without thermal problems. To facilitate maximum air ow, ensure that no objects such as rack doors or
lids are placed at the front or rear of the rack. Never attempt to reverse the airow. Make sure an adequate air
supply is provided in front of the D Series device, and that the rear of the device has sufcient space to allow
air to escape. It is recommended to keep the ambient temperature around the device as cool as possible. An
increased temperature can have a signicant negative impact on the expected lifetime on the components
inside the D Series device.
NOTE: Fit solid blanks (not ventilation blanks) to unused rack spaces to ensure effective air circulation. Leaving
gaps in between items of equipment degrades the effectiveness of forced-air cooling.
If installing one or more D Series devices in a rack with other fan-cooled equipment, conrm that all other
equipment also uses front-to-rear airow for cooling. If this precaution is not observed, there is a risk of
overheating, as units with the reverse airow will be drawing in air which has already been heated by the
D Series devices.
The D Series device is equipped with a sophisticated temperature sensing system which protects it from any
overheating which may occur as a result of inadequate ventilation.
6.4. Operating voltage
D Series has a universal power supply and its mains nominal and operating voltages are specied in the Technical
Specications. D Series can be ordered with a variety of mains plugs. If the mains plug (AC plug) tted to the mains
cable (AC cord) is not appropriate for your country it can be removed and a locally–sourced one tted instead. If
you are not 100% condent of your competence to replace the mains plug (AC plug), the task should be carried
out by qualied personnel.
NOTE: In–rush current is controlled and limited during the soft–start sequence. This enables multiple D
Series Devices on the same AC mains circuit to be turned on simultaneously.
