Chapter 2 Installation and Configuration
Installing the Amplifier Module
The amplifier module plugs into the strand-mounted or pedestal-mounted (bottom) of
the housing via RF connectors on the bottom side of the module.
Amplifier housings and amplifier modules are designed so that you can orient the
Amplifier housings and amplifier modules are designed so that you can orient the
amplifier module conveniently for maintenance. Because the input and main output
ports are located diagonally across from each other, the amplifier module is reversible.
This allows you to orient all amplifier housings to open either to the road side or to the
field side. The amplifier is then installed in the appropriate position, either right side up
or upside down.
To Install the Amplifier Module
Complete the following steps to install the amplifier module.
1
Perform the following if you are working with an amplifier station where AC is
present.
CAUTION:
RF connectors and housing seizure assemblies can be damaged if AC shunt
RF connectors and housing seizure assemblies can be damaged if AC shunt
power directors are not removed from the amplifier before installing or
removing the amplifier module from the housing.
Install the AC shunt power directors in the amplifier after you install the
amplifier module in the housing.
Remove the AC shunt power directors from the amplifier before you remove the
amplifier module from the housing.
2
Orient the amplifier module so the Input and Main output ports (the locations of
which are stamped on the module cover) are in the proper corners for your
installation.
3
Line up the RF connectors on the amplifier module and the housing, and then push
the amplifier module into the housing.
4
Secure the amplifier module to the housing by tightening the four system amplifier
module retainer screws. Tighten slotted head screws to 6 in-lb to 9 in-lb (0.7 Nm to
1.0 Nm), or cross head screws to 18 in-lb to 20 in-lb (2.0 Nm to 2.25 Nm). See the
following illustration for the location of the retainer screws.
