1.5 Installation PrerequisitesIt is absolute required that the installer pays attention to the valid EMC instructions.All other equipment on site must be CE designated and must provide interfaces for con-necting of external cables conformable to EMC instructions.

1.6 Handling of the ModulesAll boards and modules must be handled with extreme care as each one contains elec-trostatically sensitive devices (ESD). The modules are marked with the ESD-label.

Figure 1 ESD Symbol

These are sensitive to static discharge.Notice: Avoid handling the modules in a high-static environment When handling the modules, do not touch connector contacts An earthed high-impedance wrist strap must be worn when handling modules. Use the socket at the racks for wrist strap connection. The modules must be transported in appropriate packing

1.7 Installation ToolsThe correct rack installation is carried out with the aid of the following tools: Standard toolkit for BSS-installation Spirit-level

2.1 Position in the SystemThe BS21 interconnects the MS via the Um interface with the trunk network via the Abis interface.

Figure 2 Position of the BS21 within the SBS

2.2 Site RequirementsPrior to the commencement of the installation, the site must have been prepared as follows: The site specific-base construction must have been mounted. A concrete base of sufficiently large to accommodate shelter size and weight is

needed for rural sites. The distance between the enclosure sides and vertical faces i.e. walls etc. should

be restricted to 500 mm minimum.This avoid the risk of air flow restrictions into the cooling system. Adequate clearence should be provisioned in front of the enclosure in order that the shelter door may fully opened. Adequate clearence should be pro-visioned above the BS21 in order that the roof may be suffciently opened for service, maintenance or replacement purposes.

The installation area should be clear of standing water, fallen leaves, mud and building debris. Check the location for possibility of flood disasters and exessive fall of snow.

Measurements should be taken against unauthorized access. The lightning and grounding systems must be complete. All installation works of 230 V/120 VAC(BS21E/BS21U) power supply ,including a

ground fault indicator (GFI/FI) in each phase, must be finished.The BS 21 shelter should be mounted, after all other work to create the required infra-structure (antennas/antenna cabling,PCM lines...) is complete.Note, that the installation of the BS 21U is not allowed without plinth and cable entry cover!

2.2.1 Environmental ConditionsThe location of a site may directly effect the correct operation of the base station.In terms of exessive salt contamition situations it is recommended not to place the BS21 close to coastal areas in order to avoid necessarily of shorter maintenance intervals. It is recommended to keep a distance of about > 1000 m to coast. Enclosures on coastal sites should not be installed with the right hand side air intakes facing directly into pre-vailing sea winds or spray.Installation under trees and foliage is not recommended due to increased levels of insects etc. which may be drawn into the cooling system by the fans.In areas of much fall of snow the base station should be placed at an socket or at the mast with an appropriate height, so that the air intake (lower grille) will not be blocket by snow.

In potential areas subject to flooding the base station should not be placed on ground, because the base station is not protected against water ingress on bottom.Sites located close to exessive airborne dust clouds i.e. cement, coal deposits etc. should also be minimised in order to avoid contamination of the cooling system and increased maintenance.The max. open air temperature must not exeed 45C/117F.

2.3 Site ConfigurationAdditional equipment is necessary for the operation of the BS21 on site.

2.5 Equipment DeliveryThe shelter and the plinth are delivered mounted on a timber/polyurethan transportation pallet with the overall dimensions 1500 mm x 1300 mm x 700 mm (HxWxD). The pallet is bolted directly to the shelter frame. Bolt holes are located in the framework lower cross-member front and rear, 6 positions. Depending on the pre-installed modules inside the shelter, the pallet can weigh up to approx. 125 kg.The BS21 is suitably protected for transportation using a combination of bubble-wrap/ polystyrene bufferswithin an outer cardboard casing. The individual support plinth is separately packed and than taped on top of the enclosure casing ready for transporting.Additional cartons contain all equipment parts weigh over 1.00 kg:RF modules: Power Amplifiers Transceive Processor Units Power Supply Equipment AC/DC Converters Cabel Entry CoverThe transmission equipment are not content of the delivery.All crates have information printed on them for identification of delivery.Handle each carton containing installation materials with extreme caution to avoid tipping.

2.5.1 Transportation, Loading and Unloading of the BS 21The shelter crate should be transported on an air-suspensioned truck, equipped with a capable of carrying min.1.0 tonnes payload, 4 WD recommended. For loading and unloading a forklift truck or an articulated tyre crane should be used.Movement of the shelter should be supervised by personnel qualified in heavy lifting and safety. All personnel must be properly attired, wearing a safety helmet, safety boots and protective gloves.To load the shelter onto the transporting vehicle, proceed as follows: Maneuver the forklift truck, with its forks lowered, to the center of the base of the

shipping crate. When the forklift is in the correct position, an adjustable strap has to be positioned

around the crate and secured to the forklift mast eyebolts. Pull the strap tight. If the shelter has to be transported without the shipping crate, insert packing

between the forklift tower and the shelter for protection. Raise the crate until it is at a suitable height to load onto the transporting vehicle. Lower the crate onto the transporting vehicle. Remove the strap and packing. Secure the crate to the transporting vehicle. (This operation is the responsibility of

the company transporting the crate.)To unload the crate from the vehicle use a tyre crane and proceed with the following steps: Release the straps etc. securing the crate to the transporting vehicle. Maneuver the crane boom into position exactly above the center of the shipping

crate.

2.7 Security Features and Door Opening ProceduresAll exterior fixings for the BS21 are hex headed pin-torque bolts. Removal of these requires an appropriate hex pin-torque driver. Cabinet roof fixings are all accessed from inside the enclosure. The left-hand roof hinge is reversed to prevent illicit removal of the roof assembly.Each of the cabinet doors utilises a 3 point bar locking system, which secures the doors in the top, center and bottom position. The locking of the door is achieved via an EMKA Euro Cylinder. 3 off EMKA Euro Cylinder keys are supplied suitably bagged-up and tapped within the cabinet.Further an EMKA angled 8 mm drive key for operation of the 3 point bar locking system is supplied suitably bagged-up and tapped within the cabinet.A door locking alarm system is fitted to both doors and will trigger a remote alarm should the doors be opened in any manner other than that for which they were designed. The alarm system gives warning of doors in closed or open position.The locking mechanism of the cabinet has a factory fitted posi-head self-tapping security screw in place, which ensures that the cabinet cannot be inadvertently locked with the cylinder keys inside, either during factory build, transportation or installation.The opening of the doors is as follows: Insert the 8 mm square drive key and the Euro Cylinder key. Turn Cylinder key 1/2 turn clockwise to the spring position (resistance against the

key) Holding the Cylinder key on the spring, turn the 8mm square drive key 1/4 turn clock-

wise - this operates the 3 point bar locking system. Release the Euro Cylinder key.The closing of the doors is as follows: Turn the 8mm square drive key 1/4 turn anti-clockwise (this moves the 3 point bar

locking system to the locked position). Ensure that the locking bar has correctly engaged behind the top and bottom

keepers. Turn the Euro Cylinder key 1/2 turn anti-clockwise and remove.

2.8 External Cabling Activities

All interfaces are located at the EMI-panel, accessible after removing of the top of the shelter, except the ground screws. The cable entry on the left is the access for all external cables.Note (for installation of the BS21U only): Before starting installation of Data Circuits and External Interconnection Cables pay attention to the 1996 NEC, Section 725-41(a)(4). This document will consider ITE Limited Power Sources equivalent to NEC Class 2 sources for purposes of applying Article 725 wiring requirements. If data circuits could not use Article 725 wiring methods, then they would have to comply with the require-ments in Chapter 1 thru 4 of the NEC.Transient voltage surge surpression and primary protectors are not required at the entry of the wiring to the BS21U if the exposed wiring is limited to less or equal 140 feet. Refer to NEC Article 725 c) and 800-30 for proper clearance of data wiring from power and lightning conductors. The corresponding Canadian Electric Codes (CEC) sections to NEC 800-30 are CEC 60-200 and 60-202. The corresponding CEC sections to NEC 725c) are CEC 16-200 thru 16-256.Refer before starting the installation of the antenna connections to NEC Article 810. The corresponding CEC Articles to NEC 810 is Section 54.Removal of the roof the shelter is as follows: With shelter door open,release the 3-off roof retaining screws. Open the roof and release the earth cable. Undo the screws securing the right-hand hinge of the roof. Slide roof off left-hand hinge. Remove hinges from roof and swap to opposite side (fixing points already provi-

sioned).Fit only left-hand hinge to roof.After all external cable connections are installed, for re-fitting of the roof proceed in the following steps: Slide roof hinge onto enclosure left-hand hinge pin.

2.8.4 Abis-Interface - PCM Link TerminalThe Abis interface, located on RCAP, is terminated with the Overvoltage Protection (OVPT) which protects the LI inside the BS20 against overvoltage (residual voltage < 1 kV). Two types of OVPT are exist (for 75 Ohm or 120 Ohm cables). Dependend on the different cable impedances is recommended to: Use screened cable containing 8/10 shielded twisted pairs 0,25 mm2 for 120 Ohm

PCM lines, e.g. S-09YS(ST)CY 8x2x0.6/1.2. Use coaxial cables for 75 Ohm wiring, e.g. 2YCCY 0.4/2.5.The maximum cable length depends on the attenuation of the cable, in order to fulfil the requirements of minimum voltage levels to be provided at Abis interface according to PCM standards. The cable shielding must be connected to the relevant ground pins as close as possible (in order to avoid EMC/RF interfering effects).

2.8.4.1 Abis-Interface for 120 Ohm Cable Impedance

Figure 13 OVPT with terminal block (120 Ohm)Connect the Abis-interface with twisted pair cable to the PCM link terminal as follows: Cut the cable to the required length and cut back the outer insulation (approx.19

cm). Remove the wire insulation (0,8 mm). Wrap the exposed cable shield, whitch will be fixed at the stress relieving, with

adhesive copper foil (approx. 4 cm). Fix the prepared cable close to the stress relieving by straps. Insert the wires into the terminals of the OVPT.

!WARNINGThe AC connection of the BTS has to be disconnected before working at the PCM- terminal blocks. This can be done either by pulling out the AC plug or by releasing the mains breakers outside of the BTS.Releasing the internal AC breakers is not sufficient!

BS 21 Installation

For instellation and service purposes it is useful to know, which hardware is connected to which cell. The numbering, seen from the top of the antenne pole, starts at an azimuth angle of 0 (north) and rotates clockwise. The first existing cell which beam center line lies at 0 or more degree is defined as cell 0 or sector 0. The next one following in the same direction cell is cell 1 etc. In case of omni cell the cell no. is 0.

2.11.4 Mounting of the Cabel Entry CoverAfter all external cabling works are finished and all cables fixed by the clamps of the cable entry, proceed in steps as follows: Check the correct fixing of all connectors at the EMI-panel. Bend the external cables inside the EMI-panel to the correct form. Pay attention to

the minimum bending radius of each cable type. Make sure that all sealings are in the correct position. Close the top cover of the shelter and fix it by the fastening screws, located in the

upper area of the door frame. Fix all cables leaving the shelter at the holders of the cable entry cover. Use adhesive sealing tape for closing the gap between shelter and cable entry

cover. Set up the cover and tighten the 6 M6 Allen screws.The following figure will give orientation for the handling of the cable entry cover.

Note, that the installation of the BS21U is not allowed without cable entry cover! Before re-opening of the shelters top for EMI-panel access in case of extension- or mainte-nance works, the cable entry cover has been dismounted at first.

2.12 Rack ExtensionRack extension is necessary to save the antenna system and provide a 4 carrier cell with two coupled BS21. Rack extension could be realized in case of new installation of two BS21 on site or a second BS21 will be added to the already installed shelter. The follow-ing figure gives information about the minimum site dimensions.

Figure 29 Minimum site dimensions for BS21 rack extension

The distances as shown in the figure are necessary for function and maintenance of the equipment on site: approx. 150 mm between back and wall for opening the top cover approx. 500 mm between sidewall and cabel entry cover or wall for securing the

function of the air inlets and air outlets. Further the space reservation is needed for removing the cable entry cover.

min. 870 mm for complete opening of the front doorsIn case the racks are installed without base constructions, a min. distance between floor and ceiling or other lowest construction part of 1600 mm is absolute required (for opening the top cover).

2.12.1 Connections between the Racks1/2 jumper leads are required for connecting the racks, equipped with N-type female connectors at both ends. The laying of these cables requires a metal cable duct or metallic tubes between the shelters, which must be connected to ground for lightning protection.The rack extension consists of the jumper connections as shown in the figure and the rack-internal system cabling. Further a HYBRID module has to be installed in each BS21. The slots of RXAMCO 2 and 3 are the mounting position for the HYBRID.

BS 21 Installation

The extension kit, which contains the 4 jumper cables, 2 HYBRID incl. SMA adapters and the extension system cabling, is necessary for the implementation of rack exten-sion. Proceed in following stages: Open the top cover and the front doors of both racks. Install in each rack one RXAMCO and the HYBRID module. Prepare the stripes at the EMI-panel for fitting of N-type male connectors. Unscrew the EMI panel and lift it up in open position. Substitute the input isolator of the TXin 0 connector by an SMA adapter. Insert the prefabricated connecting cables between EMI-panel and RXAMCO. Fix the N-type connectors at the stripes. Lift back the EMI-panel and fix it by the screws. Fix the stripes at the EMI-panel. Lead the flexible RF-connecting cable to the front connectors of RXAMCO and TPU

and fix them in accordance with Tab.2.20.

For completion of the rack-internal cable the following connections are necessary in both racks:

The last step of the extension works will be the connecting of the racks to the trans-mit/receive antennas. The BS21 called 0 has to be connected via 1/2 jumper cable to TX/RX antenna 0. Rack 1 has to be connected TX/RX antenna 1. Both antennas serving the same sector (0).
