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 ARA-1 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 within specifications.
NOTE:
If the ARA-1 is installed in a high RF environment such as a 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 ARA-1.
NOTE:
For the DC input, the plug is the equipment disconnect device.
