4.1 Unpacking the unit
4. Setting up the amplifier
DPI amplifiers are packed in a strong cardboard box that pro
-
tects it during transport. In case you ever need to ship the ampli-
fier again it is best to pack it using the original packaging materials.
Therefore it is advised to save all packaging materials.
The packaging has been specially studied for low load to the
environment. The individual packaging materials can be easily
separated and recycled.
Please inspect the unit carefully for any signs of damage
incurred during transport. This DPI amplifier has undergone
stringent quality control inspection and tests at the factory. It
left in perfect condition. If damage is found notify the transport
company immediately.
It is important to immediately mount the fanguard that is
included in the box. It is an integral part of the electrical safety
provisions of the unit.
When repacking the unit, use the same packing
arrangement as shown in the picture. Make sure
to remove the fanguard. Place it on the side of the
unit, between the two side buffers. This protects the
fanguard during transport.
Warning: Before continuing the installa-
tion of the DPI amplifier, mount the fan
-
guard on the front of the unit.

Place the two tabs of the fanguard in the corresponding holes
on the right of the unit. Push the fanguard against the front panel
and secure it by turning the /4 turn lock 90° clockwise.
DPI series amplifiers are equipped with two cooling fans with
front to rear airflow. When installing the amplifier, allow for ample
space behind the amplifier to ensure sufficient airflow, especially
if the amplifier is operated in a rack system. This avoids thermal
limiting of the output power or, in severe situations even shut-off
by the thermal protection system.
The fancover can be easilly removed by turning the /4 turn
lock 90° counterclockwise and pulling it off the frontpanel, left
side first.
The standard air filter delivered with the amplifier is a black,
8mm thick reticulated polyurethane foam with a density of 20PPI.
The filter can be easilly cleaned by rinsing it with water. Let it dry
thouroughly before mounting it back onto the amplifier.
In case you need to replace the filter use only the prescribed
material and thickness or contact your distributor for a replace-
ment.
Do not use the amplifier without the airfilter in place.
Regular cleaning of the filter eliminates dust buildup inside the
unit.
