Aug 14 Page 14 ENVIRONMENTAL CONDITIONS
If multiple bases are fitted in a rack, auxiliary extractor fans may be required to ensure that
adequate cooling is provided.
If any other configuration is employed, the performance of the system will depend on how closely
you comply with the airflow requirements described above.
In a wall mount installation, it is recommended that at least 20 cm of clear space is allowed above
and below the equipment for ventilation.
Equipment rooms as a whole should be checked for adequate ventilation so that they do not
overheat.
Correct operation of internal fans should be checked prior to completion of the installation.
Any secondary ventilation equipment (rack fans, grills etc.) should be checked for correct operation
and to ensure that they are free from blockage. Filters are not recommended on enclosures unless
they can be regularly maintained.
MOUNTING LOCATION
A clean and dry location that meets the above ventilation requirements should be chosen for
mounting the equipment. The unit should not be sited where it will be exposed to long periods of
direct sunlight.
Provision should be made for bringing the antenna feeder(s), IP cables, station earth and the AC
and/or DC supply leads to the installation. These cables must be firmly anchored, in accordance
with good installation practice and comply with all local mandatory wiring requirements.
WALL MOUNT
When installing the wall mount unit, it is essential that the vertical surface chosen for the
positioning of the equipment is of a solid construction as the weight of the SDB680 Base Station
can be as much as 10 kg when fully equipped.
