3.3 Installing the equipment
It is recommended that all peripheral equipment (e.g., repeaters, splitters) as well as the engineering
accessories should be installed before installation of the Terminal Station.
3.3.1 Information required for installation
Appendix 1 – 7390 TS installation sheet contains a sheet for you to complete and collect all the
general information needed for the installation procedure.
3.3.2 Precautions concerning electromagnetic compatibility
Installation is designed to meet all new requirements concerning electromagnetic compatibility and
safety.
The performance of the equipment depends on installation practices (cable installation, ground
connections, etc.) which should be based on best trade practices and which may be degraded if these
practices are not respected.
3.3.3 Tools required
The installation staff must possess a standard installation toolkit (containing, in particular: drill, drill bits,
soldering iron, cable tie pliers, terminal pliers). A heating pack is also required for heat-shrinking
operations.
The list of tools required for the mechanical installation of the Terminal Station is given below:

3.4 Installation of the Terminal Station RT unit with an inte-
grated antenna
Considerations:
The installation of the RT unit should satisfy the following criteria:
–unimpeded direct line of sight between RT unit and RBS (Base Station),
–perfect mechanical rigidity,
–enabling precise antenna alignment.
The 7390RT is designed for outdoor installation without any particular protection. However, the following
recommendations must be respected:
–do not install equipment below bird nesting areas,
–do not attach equipment to a surface prone to vibrations (machinery, lift housing, air conditioning,
etc.),
–do not attach equipment to chimneys which give off fat deposits, dust and other aerosols which
are liable to come to rest on the equipment,
–do not install equipment in proximity of sources of heat,
–do not place the equipment in proximity to corrosive gas outputs,
–do not place the equipment below roof run-offs not equipped with guttering (high risk of microwave
short-circuit),
–do not install at man-height to prevent human collisions against the antenna. This could cut the
radio link with the central station.
Two types of assembly are possible:
–on a flat, vertical surface (e.g., a wall),
–on a pole/tube (existing or to be installed), using threaded U-bolts and nuts (M8).
Note: The pole/tube selected should be sufficiently rigid to prevent antenna misalignment and resist
vibrations.
Use tube supports that comply with our recommendations. Support references are mentioned in
the next chapters.
3.4.1 Definition of assemblies with respect to chosen polarization
The Terminal Station RT unit can be mounted with horizontal (H) or vertical (V) polarization.
To mount the radio/antenna assembly on the support arm, in the event of horizontal polarization, the
horizontal polarization kit must be used. This consists of an additional joint to compensate for the
mechanical rotation of the system.
IMPORTANT NOTE: NEVER HANDLE THE RT UNIT BY ITS ANTENNA BUT BY
THE BODY OF THE RADIO OR THE SUPPORT ARM
USE THE SAME POLARIZATION ON TERMINAL STATION AND BASE STATION

The pole-mounting mechanical assembly consists of (Figure 11 – Support arm components):
–two components in the case of vertical polarization (V): wall mounting (ref.1) and bearing moun-
ting (ref.2);
–three components in the case of horizontal polarization (H): wall mounting (ref.1) , bearing moun-
ting (ref.2) and polarization mounting (ref.3).
Figure 11 – Support arm components
A polarization slot indicator at the rear of the RT unit can be checked to confirm that the assembly is
correct with respect to the chosen polarization:
–if the letter "H" can be read naturally, polarization is horizontal,
–if the letter "V" can be read naturally, polarization is vertical,

3.4.2 Installation of the 7390 RT on a wall or flat vertical surface
Considerations:
–If attaching the RT unit using bolts and plugs, select the attachment components to suit the com-
position of the attachment surface.
–The surface chosen should not be prone to vibrations (e.g., avoid machine housings).
–To mark the drill holes, use the drilling template printed on the inside panel of the RT unit packa-
ging box.
Figure 14 – Installation of the RT unit on a wall
Stages
1. Select the installation location and determine the polarization of the RT unit.
2. Place the drilling template against the wall (or surface) to be pierced.
Note: The vertical axis of the wall mounting assembly must be respected (see Figure 15 – Wall moun-
ting). Used a bubble level or inclinometer.
3. Drill the 4 holes.
4. Insert the 4 plugs.
5. Install and secure the wall mounting (V et H polarization) using four M6x50 screws with washers.
Note: Screw torque = 4.3 to 4.9 m.N.

6. Install and secure the bearing mounting on the wall mounting (V and H polarization).
Figure 16 – Screws mounting
To continue the hardware installation, go to step 7 in the case of horizontal polarization or go directly to
step 8 for vertical polarization.
7. Install and secure the polarization mounting (H polarization only).
8. Install and secure the RT unit on the support arm. Check on polarization indicator that the
polarization assembly is correct (cf. Figure 12 – Vertical Polarization and Figure 13 – Horizontal
polarization).
9. Release the RT assembly locking screw and carry out antenna prepointing visually and/or using a
compass and a map. To do this, orientate the assembly so that the antenna is pointed towards the
Base Station antenna.
10. Remove the radio module from its axis for configuration (see Chapter 4 Commissioning the 7390 TS
Terminal Station).

3.4.3 Installation of the RT unit on a tube for «N» or «F» connector RT
Considerations
–Install on tube using two U-bolts.
–Installation may be carried out on a newly installed or existing tube.
–The external diameter of the tube is 76 mm in standard configuration.
–The support tube, along with the U-bolts, must be clean and (apart from threads) grease-free.
–If specific site features make perfect alignment impossible (line of sight parallel to the wall, for
example). You are recommended to use a support that complies with our specifications (see re-
ferences in the paragraphs which follow).
Note: The use of supports with slenderness ratios inferior to our own is authorized (more rigid).
Note: Slenderness ratio = length / cross-section of sections used.
Steps
1. Select the installation location and determine the polarization of the RT.
2. Install and secure the wall mounting (V et H polarization) using the two U-bolts (and nuts with
washers) provided for this purpose, or the attachment hardware delivered with the specific wall
mount.
Note: Screw torque = 10.5 to 12 m.N.
Note: The vertical axis of the wall mounting assembly must be respected.
3. Install and secure the bearing mounting on the wall mounting (V and H polarization), see Figure 11
– Support arm components.
To continue the hardware installation, go to step 4 in the case of horizontal polarization or go directly to
step 5 for vertical polarization.
4. Install and secure the polarization mounting (H polarization only).
5. Install and secure the RT radio unit with its antenna on the support arm. Check the polarization
indicator to check correct polarization (cf. Figure 12 – Vertical Polarization and Figure 13 – Horizontal
polarization).
6. Release the RT assembly locking screw and carry out antenna prepointing visually and/or using a
compass and a map. To do this, orientate the assembly so that the antenna is pointed towards the
Base Station antenna.
7. Remove the radio module from its axis for configuration (See Chapter 4 Commissioning the 7390 TS
Terminal Station) to make commissioning easier.
