3CC12423AAAA TQ BJA 01 Issue 01 - March 2001 - Draft 03 29/ 114523.3 Installing the equipmentIt is recommended that all peripheral equipment (e.g., repeaters, splitters) as well as the engineeringaccessories should be installed before installation of the Terminal Station.3.3.1 Information required for installationAppendix 1 – 7390 TS installation sheet contains a sheet for you to complete and collect all thegeneral information needed for the installation procedure.3.3.2 Precautions concerning electromagnetic compatibilityInstallation is designed to meet all new requirements concerning electromagnetic compatibility andsafety.The performance of the equipment depends on installation practices (cable installation, groundconnections, etc.) which should be based on best trade practices and which may be degraded if thesepractices are not respected.3.3.3 Tools requiredThe 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-shrinkingoperations.The list of tools required for the mechanical installation of the Terminal Station is given below:FOR INTEGRATED ANTENNAFigure 10 – - InclinometerTool Use5 mm Allen key (for M6 screw) For securing the pole mounting and wall mounting13 wrench For tightening the U bolts on the 40 to 50 mm tubeLevel gauge or inclinometer For vertically of the bearing axis

3CC12423AAAA TQ BJA 01 Issue 01 - March 2001 - Draft 03 31/ 114523.4 Installation of the Terminal Station RT unit with an inte-grated antennaConsiderations: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 followingrecommendations 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 whichare 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 microwaveshort-circuit),–do not install at man-height to prevent human collisions against the antenna. This could cut theradio 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 resistvibrations.Use tube supports that comply with our recommendations. Support references are mentioned inthe next chapters.3.4.1 Definition of assemblies with respect to chosen polarizationThe 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, thehorizontal polarization kit must be used. This consists of an additional joint to compensate for themechanical rotation of the system.IMPORTANT NOTE: NEVER HANDLE THE RT UNIT BY ITS ANTENNA BUT BYTHE BODY OF THE RADIO OR THE SUPPORT ARMUSE THE SAME POLARIZATION ON TERMINAL STATION AND BASE STATION
32/ 114 Issue 01 - March 2001 - Draft 03 3CC12423AAAA TQ BJA 0152The 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 componentsA polarization slot indicator at the rear of the RT unit can be checked to confirm that the assembly iscorrect 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,Figure 12 – Vertical PolarizationFigure 13 – Horizontal polarization123bearing mountwall mounthorizontal polarizationmountonly with the RT cubevertical axisvertical axisvertical axis
3CC12423AAAA TQ BJA 01 Issue 01 - March 2001 - Draft 03 33/ 114523.4.2 Installation of the 7390 RT on a wall or flat vertical surfaceConsiderations:–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 wallStages1. 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.IMPORTANT: VERTICALITY OF ± 1° REQUIRED FOR POLARIZATION

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.Steps1. 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 withwashers) provided for this purpose, or the attachment hardware delivered with the specific wallmount.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 tostep 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 polarizationindicator to check correct polarization (cf. Figure 12 – Vertical Polarization and Figure 13 – Horizontalpolarization).6. Release the RT assembly locking screw and carry out antenna prepointing visually and/or using acompass and a map. To do this, orientate the assembly so that the antenna is pointed towards theBase Station antenna.7. Remove the radio module from its axis for configuration (See Chapter 4 Commissioning the 7390 TSTerminal Station) to make commissioning easier.IMPORTANT: VERTICALITY OF ± 1° REQUIRED FOR POLARIZATIONIMPORTANT NOTE: THE USE OF SUPPORTS WITH A SLENDERNESS RATIO GREATER THAN OUR MODELS SHOULD BE EXCLUDED (TOO FLEXIBLE)
