Installation Considerations
Careful attention to the following installation suggestions should result in the best unit/system
performance. The unit is 1.36 inches tall, and 6.5 inches wide by 6.5 inches deep.
The NXU-2B must be installed in a structure that provides both protection from the weather and
assurance of ambient temperatures between -20 and +60 degrees C. Since the unit is neither
splash proof nor corrosion resistant, it must be protected from exposure to salt spray. When the
unit is mounted in a cabinet with other heat-generating equipment, the use of a rack blower is
suggested to keep the cabinet interior temperature rise to a minimum.
NOTE: If the NXU-2B is installed in a high RF environment such as repeater system
or other transmitter site, it is recommended that all cable assemblies be individually
shielded, with the shield grounded to the ground pin on the terminal block for that
module. For all D-subminiature connector cable assemblies, cable shields should be
connected to connector shells so that they make contact with the grounded D-
subminiature connector shells on the NXU-2B.
