the manufacturer or supplier. All electrical products sold
in the EC must be approved for immunity against
electromagnetic elds, high voltage ashes, and radio
interference.
• Consult the dealer or an experienced radio/TV technician
for help.
3.4.4. Speaker damage
Amplier apparatus is very powerful and can be potentially
dangerous to both loudspeakers and humans alike. Many
loudspeakers can be easily damaged or destroyed by
overpowering them. Always check the speaker’s continuous
and peak power capabilities. Although the ampliers
attenuators can be used to reduce the overall gain, an
increase of the input signal can result in full output power,
which may cause damage to connected speakers.
3.4.5. Maintenance
For safe and reliable operation, the dust lters on both sides
of the front panel, behind the grilles, should be removed and
cleaned regularly to ensure maximum airow through the
device.
If the dust lters are not maintained there will be safety
risks; for example, high internal temperatures could ignite
the dust and start a re. There is also a risk that the unit
will malfunction since it is dependent on constant airow
from front to rear. If the dust lters are not clean and the unit
malfunctions, any resulting problems will not be covered by
the warranty.

6.2. Mounting
D Series is made for mounting in 19 inch racks. Four screw holes are available for attachment of the amplier to
the rack’s front rack rail. This device has no top or bottom vents; therefore, units may be stacked directly on top of
one another. Sufcient space should be available at the rear to accommodate connectors and cables. In addition,
allowance must be made for cable or loom bends within a rack.
6.2.1. Rear Mounting
Two rear support brackets, along with associated mounting hardware, are included with the D Series device. It is
strongly recommended that these are used wherever possible. Fit the brackets to the vertical rails at the rear of
the rack. The support brackets are reversible and may be tted to point either to the front or rear of the rack; the
proper orientation depends on the rack depth and position of the rear rack rails.

6.2.2. Mounting front grille
The front grille is shipped on top of the amplier inside the box to protect it during shipping. The front grille adheres
to the amplier 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.
6.3. Cooling and fan operation
D Series devices use a forced-air cooling system with airow 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 airow. Make sure an adequate air
supply is provided in front of the D Series device, and that the rear of the device has sufcient 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 signicant negative impact on the expected lifetime on the components
inside the D Series device.
NOTE: Always ensure the dust lters behind the detachable front panel are clean to ensure maximum
possible airow. 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 amplier without the dust lter installed.
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, conrm that all other
equipment also uses front-to-rear airow for cooling. If this precaution is not observed, there is a risk of
overheating, as units with the reverse airow 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 specied in the Technical
Specications. 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% condent of your competence to replace the mains plug (AC plug), the task should be carried
out by qualied 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.

6. Installation
6.4.1. Low voltage country considerations
Although the D Series has a wide range of operating mains voltage, some considerations can be applicable for
low voltage regions. D Series performs well throughout the specied nominal voltage range but has slightly better
efciency at higher voltages. For regions with nominal voltage below 140 V, one could consider connecting the
amplier in a three–phase delta or two phase split–phase conguration.
NOTE: Following connections applicable only for resulting voltage inside the ampliers nominal voltage
range.
Connecting the amplier in three phase delta conguration
In three–phase conguration where the phases are 120 degrees apart, one can connect three balanced loads in a
delta conguration. The connection is made between the phases instead of between the neutral and a phase.
