Rack Mount Instructions
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be
greater than room ambient. Keep the rack environment temperature at or below the maximum ambient temperature (Tma)
specified by the manufacturer of the installed equipment.
Provide the proper amount of air flow inside the rack as required for safe operation of the equipment.
Do not create a hazardous condition by mounting the equipment in the rack with an uneven mechanical load.
When connecting the equipment to the supply circuit, consider the effect that overloading of the circuits might have on
over-current protection and supply wiring. Consider all equipment nameplate ratings when addressing this concern.
Maintain reliable earthing of rack-mounted equipment. Give particular attention to indirect supply connections to the
branch circuit (e.g., power strips).
System Installation
Installing Front-Mounted Antennas
The UA845UWB comes equipped for front-mounted antennas. Front-mounting improves RF performance of the system by
moving the antennas to the front of the rack. When a unit is located in a rack, antennas should be either front- or remote-
mounted.
Insert the bulkhead adapters through the holes in each bracket, and secure them from each side, using the supplied
hardware.
Connect the supplied antenna cables to the receiver antenna inputs and adapters.
Install the antennas onto the bulkhead adapters protruding through the front panel.
Note:
For the best results, point the antennas up and away from each other at 45° angles from vertical. This ensures the best possible reception and greatly
reduces the possibility of signal dropout. Always perform a walk-through test of the system in the performing area before using a wireless system.
