III. INSTALLATION
The Programmable Bi-Directional Booster Amplifier is housed in a steel
NEMA 4 enclosure. The enclosure has four mounting tabs on its rear surface
(refer to drawing 50483-05-17).
In selecting a mounting surface, the size and
weight of the unit must be considered.
The RF cables to the radiators (distribution system) are connected to
female N-connectors on the bottom of the enclosure. Special care should be
taken in the dress and separation of theses cables to prevent signal coupling
between the input and output of the PBBA.
The PBBA requires a 110VAC power source. It is recommended, to
maintain the integrity of the NEMA enclosure, that the AC power should enter
using conduit or a connector. A cutout for a ¾” conduit connector is provided at
the bottom of the enclosure.
Connect the unit as follows:
RF CABLE CONNECTIONS
(refer to drawing 50483-01-18):
1)
Talk Out:
to radiating cable run to 8-Channel Booster Amplifier.
2)
Power:
to AC conduit.
3)
Com Port:
for calibration only no connection required at installation.
4)
Talk In:
to radiating cable run to end of tunnel.
AC POWER INTERCONNECT
(refer to drawing 50483-01-15):
The AC power signals are connected to an internal terminal block. The
terminal block is located on the top plate assembly at the right of the lower edge.
Connect the AC sources as follows:
1)
The ground wire from the AC conduit connects to terminal 1.
2)
The AC high wire from the AC conduit connects to terminal 2.
3)
The neutral wire from the AC conduit connects to terminal 3.
