10000010334-01 of 36

5. Installation of TTA

1. Transport crate containing antenna assembly to an area below the final installation position. Where possible the top of assembly should be directly below the support structure.

2. Remove top and sides of the transport crate.

3. Prepare appropriate site and rigging equipment for the height of the support structure using preferred engineering practice. Two lifting arrangements are shown in APPENDIX B and APPENDIX C.

4. Refer to accompanying table for typical installation Rope lengths. Ensure the appropriate length is on hand for each site. Rope Datasheet see APPENDIX D

5. Locate the hand winch (e.g. Rig-Mate (Datasheet in APPENDIX E) creeper or Tirfor hand winch) for the 16 mm running line away from the tower, and where the operator has clear view of the full height of the tower, the antenna load, and all personnel involved in lifting the antenna load. A distance measure-ment cannot be specified exactly – safety of people and equipment determines this location and the guides above are an estimate only. Fix the winch in place using a dead weight (heavy vehicle) or ground anchor. Install the Tirfor handle and the Tirfor wire rope in the Tirfor. Position the eye end on the load side of the Tirfor, the tapered end feeds through the Tirfor and should be tethered to the ground anchor or dead weight. Install the running line at the tower top (about 1-2 metres above the top of the final antenna position). Run the loose end through the eye on the Tirfor. When the line is tight, the load is guided up to the tower top. Let the slack off gradually to bring the load into the correct position on the tower.



10000010334-01 of 36

6. Locate the head block (self-locking snatch block with eye) on the tower (block capacity minimum 800 kg WLL).

7. Locate the heel block (self-locking snatch block with eye) at the foot of the tower.

8. Install the main winch (Ingersoll Rand or similar drum style winch with minimum 800kg WLL) in position. Secure it with ground anchors or a dead weight.

9. Fit the eyebolts to the top flanges of the

antenna as required for each arrangement.

10. Attach winch line to uppermost eye bolts or eyebolt (using sling/rope and shackle combination or other preferred fixing method).

11. Lay the wire rope into the head block and the heel block at the top and bottom of the support tower. The eye end of the rope will attach to the eye bolts on the antenna. The free end will be wound around the drum of the winch.

12. Attach mounting hardware to the antenna assembly prior to lifting.

13. To allow removal of the transport crate securing hardware, take the weight of the assembly with the winch. Keep the assembly steady.

14. Remove the hardware (bolts, screws etc.) securing the antenna to the packing. Keep the assembly steady.



10000010334-01 of 36

15. Raise the top of the assembly to a vertical position. Steady the assembly to avoid damage. The base flanges slide along the crate as the assembly goes vertical.

16. With the assembly base resting on the transport crate and steadied to avoid damage, attach extra sling/rope and shackles, lifting hook to remaining top flange eye bolt.

DO NOT RELEASE THE

EXISTING SLINGS FROM

THE LIFTING HOOK.

Some adjustment may be necessary so that the antenna assembly hangs vertical from the winch line and the load is shared by all lifting eyes. It will be an advantage to use slings all of the same length (refer to accompanying picture).

17. Attach tag lines to the base of the assembly as shown on the appropriate rigging arrangement diagram.

18. Slowly lift assembly to installation position using the tag line to avoid contact between antenna assembly and the mounting pole.

19. Once antenna assembly is in final position (this can be managed with the tag lines), attach the mounting brackets and tighten securely.

20. Remove lifting hardware from the eye bolts. (lifting eye bolts can remain as part of the assembly). Mount the antenna with the radome facing the direction of desired radiation. Mounting clamps are supplied.



10000010334-01 of 36

6. TTA Azimuth Adjustment

DO NOT loosen any

fastening nuts clamped

with tower pipe during

azimuth adjustment!

1. Unscrew hoisting hook from top flange.



10000010334-01 of 36

2. Loosen 4 x M12 fastening nuts from each clamp (opposite side of tower pipe)

- In total 12 nut from 3 clamps (top, middle,

bottom)

DO NOT remove these

nuts completely. Just

loosen slightly to allow

settling of TTA

3. The whole frame will slip down due to weight and will be stopped by the flange at the bolted clamp.



10000010334-01 of 36

4. Rotate RFS TTA system to desired azimuth manually (-60° to +60°)

5. Re-tighten the 12 pcs M12 nuts by sequence (torque: 60 Nm)



10000010334-01 of 36

7. Mounting of a riser cable in the box

Use a standard cable clamp to temporarily attach the riser to the infrastructure. This will simplify the assembly process.

Open the riser grounding bar by loosening the corresponding screws.

Tools required: Phillips (cross) screwdriver

Feed fiber optic cable from the riser cable through the cable gland and the grounding bar. Start with the bottom left gland (grounding bar marked in green).

Caution: Do not remove the

protective bubble wrap foil

because it will make the

insertion process easier.

To minimize the risk of

increased fiber attenuation,

do not kink or bend the

cable too sharply.

To minimize the risk of



cable too sharply.

Temporarily attach the fiber optic cable to the over length holder.

Feed the DC cable and armor of the jumper through the cable gland and the grounding bar.

Attach the grounding bar to the armor and tighten to mechanical stop.




10000010334-01 of 36

In case only three jumpers are connected (3 sector scenario) the fourth fiber pair of the riser cable should be terminated with a “loop back connector”

Connect the DC cables to the screw terminal. Match each cable to its corresponding color-coded terminal.

Tools required: Flat head screwdriver

Lay the fiber optic cables counter-clockwise into the over length holders and terminate each cable at the fiber optic adapters.

Make sure that the fiber optic connectors with a red boot are connected to the bottom adapter (marked red), and that the connectors with a blue boot are connected to the top adapters (marked blue).

Secure cable where necessary with provided cable clips.

Caution: Clean the fiber optic

connectors before

connecting them.

Use only approved

fiber optic connector

cleaning kits.

8. Hoisting & Mounting the riser

cable

Check materials to make sure all parts

are available. The following are required

to mount and adjust the riser cable:

· Pre-connectorized HYBRIFLEX Riser Cable assembly

· GKSPEED Earthing Kits (if applicable)

· Clamps (if applicable)

· Rip tool (HTRT-1-000), electrical screwdriver, pipe cutter

Unpack the HYBRIFLEX cable and

prepare it for hoisting:

· Unroll the ring on the ground. The outer part of the ring is intended to be the TOP end.

· Attach the hoisting grip to the armored part of the HYBRIFLEX TOP end.

· Attach individual DC and fiber optic cables to the hoisting rope (this can be done with insulation tape).

· Ensure that the fiber optic connectors distribution parts of the riser cable should not be unpacked before connecting it to the Distribution Box (DB) or Baseband Unit (BBU).

Hoist the HYBRIFLEX cable:

· Based on cable length and site conditions, this can be accomplished manually or by means of a winch. The maximum pulling length per hoisting grip should not exceed 50m. If a second hoisting grip is needed, make sure the cable between the hoisting grips hangs with a bit of slack.

· Extend the required cable length up to the entrance of the distribution box. Then attach the main part of the cable temporarily as near as possible to the box.

· Before removing the hoisting grip, install a minimum of three cable clamps to the top of the horizontal run to prevent the cable from slipping.



10000010334-01 of 36

· Use MBHS78-1-F (single layer) or MBHS78-3-F (triple layer) cable clamps.

· Complete all the connection work described in Section 3.

Clamping

· Install the remaining clamps, starting at the top and moving down along the structure.

· Pre-install the clamps to the structure.

· Clamp the cable into the clamps.

· Remove the hoisting grip when the clamping process is completed.

Tools required: 13 mm open-ended spanner

9. Grounding of riser cable

For this project three grounding points are foreseen:

On the top near to the distribution box

Before transition from vertical to horizontal cable run

Before entering the building / outdoor cabinet for BBU

Clean the jacket at the desired grounding point and cut out a strip of 20mm (0.8 in) with the stripping tool JSTRIP-78-2 (do not damage the outer conductor!)

Remove covering paper from Butyl carefully in direction of the arrow and pre-bend the grounding body. Align the grounding kit body to the slot (grounding wire on the bottom side) and wrap it around the cable. Make sure wire mesh keeps in place in the body and is placed in the dismantled area. Do not turn or move the body after wrapping around the cable, otherwise butyl sealing could be damaged.



10000010334-01 of 36

Tighten the two screws alternating (6-10 Nm)

Straighten the grounding wire in the direction to the grounding point (shortest way possible). The fixation of the wire is recommended. Note the standard & local rules.

Tools required: JSTRIP-78-2, Flat head screw driver, 5mm Allen key

10. Over length management

Typically, an excess length of the main cable is not stored. If installation results in an over length of HYBRIFLEX cable, the excess cable can be cut easily by removing the armor and the jacket from the excess length.

Start by determining the new break point and cut the armor and jacket using a standard pipe cutter.

The HYBRIFLEX cable is constructed with a built-in Kevlar rip cord, which allows cutting longitudinally through the armor and jacket. To simplify the cutting process, use the RFS rip tool (HTRT-1-000) with an electric screwdriver.

Remove the armor and jacket.

Tools required: Standard pipe cutter Rip Tool HTRT-1-000

Caution: Wear protective gloves

during this process!

Remove the protective foil from the inner core.

Note that DC cables can be cut to the desired length, while pre-connectorized fiber optic cables can be coiled to a handy ring that can be stored in the 19” patch panel.



10000010334-01 of 36

11. Mounting the patch panel in a 19”

inch rack

Typically, the fiber optic distribution and patch panel is mounted using a cage nut.

Hold the patch panel in position…

… and mount it using rack-screws with plastic washers. Note that these screws are not part of the patch panel package. They should be part of the 19” rack.


The drawer can be opened by raising the front panel.



10000010334-01 of 36

Feed the fiber optic cables through one of the four cable entries in the back of the drawer. The single excess cables can be secured in multiple positions using cable ties.

Caution: To minimize the risk of



cable too sharply.

Connect the fiber optic connectors to the adapters.

The dust caps on the connectors and adapters can be stored in the drawer for later use. But dust caps should be stored in dust protective packaging before storage.

Caution: Clean the fiber optic

connectors before

connecting them.

Use only approved

fiber optic connector

cleaning kits.

12. Changing jumper cables in the

field

Remove the old jumper:

· Disconnect the fiber optic connectors from the adapters and unwind the fiber optic cable from the over length holder. Disconnect the DC cables from the screw terminal.

· Open the jumper grounding bar and loosen the compression nut on the cable gland.

· Carefully pull out the jumper.

Re-attach the new jumper:
