Installation Considerations
Careful attention to the following installation suggestions should result in the best unit/system
performance. Figure 2-1 provides overall unit dimensions.
The NXU-2A must be installed in a structure that provides both protection from the weather
and assurance of ambient temperatures between -10 and +55 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-2A 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-2A.
NOTE:
For the DC input, the plug is the equipment disconnect device.
REMARQUE:
Pour deconnecter le DC, retirez la prise qui est couramment
connecte a l'equipement.
