Installing Your Amplifier: Mechanical Considerations
To ensure that this equipment performs to specification, it should be mounted in a suitable
rack or enclosure as described below. Like all high power amplifiers, it should be kept away
from other equipment which is sensitive to magnetic fields. Also, this amplifier may suffer a
substantial reduction in performance if it is subjected to, or mounted close to equipment
which radiates high RF fields.
Warning: To prevent injury, this apparatus must be securely attached to the rack in
accordance with the installation instructions
When mounting the amplifier in a rack or enclosure:
Be aware that…
THE FRONT PANEL IS NOT CAPABLE OF SUPPORTING THE UNIT ON ITS OWN.
Make sure that the rear of the unit is adequately supported. The brackets which are supplied
fit standard 19 inch (483mm) rack mounting systems.
ENSURE THERE IS ADEQUATE VENTILATION.
The cooling fans suck cool air in through the front and blow hot air out at the rear of the unit
through the ventilating grills. The front and rear of the amplifier should have free exposure to
the air (i.e. in a rack leave the front & rear doors off), with 2cm air gap at the sides.
IF AIR IS NOT ALLOWED TO ESCAPE FROM THE REAR, OVER-HEATING WILL OCCUR.
Take care when mounting other equipment in the same rack.
Make sure that the rack unit has a separate earth connection (technical earth).
Please also see the notes regarding maintenance on page 17.
Installing Your Amplifier: RF Emissions
The high frequency resonant converters in the AQ-10 have been designed to have very low
radio frequency (RF) emissions; however even these low level emissions can cause
interference with other equipment.
In order for this to be minimised, the amplifier should be mounted in a metal rack enclosure,
which should have a separate (technical) Earth. Alternatively a separate earth should be
attached to the amplifier at the rear rack mounting bracket.
