2.2 Site RequirementsPrior to the commencement of installation, the construction of the room in which the base transceiver station is to be housed must be complete and the room in good condi-tion and dry - heaters, if necessary, should be put up in the room. Dependend on the power consumption of the BS20, the AC mains output of the power supply equipment must provide a connected load of 800 W / 3,5 A.

In case of wall mounting, a load-carrying capacity of 2.50 kN/m2 is required for hang up the BS20. If floor mounting is planned, the floor load capacity must be not less than 650 kp/m2. A minimum floor space of 1,50 m x 1,50 m should be provided for both mounting variants.

The BS20 is intended to be installed in a restricted access area.

Doors and windows must already have been installed and must be lockable. Openings in wall or ceiling of floor - if required - must be complete. The floor coverings must have been laid. Room lighting and wall sockets must have been installed. Heating or air-conditioning systems should be ready for operation. Walls and ceilings should have been painted.The room must be clean. A minimum floor space of 1,50 m x 1,50 m should be provided. The construction of the installation room requires the realization of lightning protec-

tion zone 1 according IEC 1312-1/DIN VDE 0185 part 103.

To prevent subsequent accumulation of dust and dirt, the parts and equipment units to be installed must be unpacked outside the room (if possible).

2.7.2 Ground and Power Supply ConnectionsA cable (3x2.5 mm) is required for connecting the BS 20 rack with the 230 V AC /50Hz mains connection point on site. An alternative connection in case of an external power supply will be used, is a 48 V DC cable (2x4 mm) to the power supply unit on site.

Depending on the site-specific power supply configuration, the rack has to be connected directly with the mains connection point or via a (optional) power distribution panel.

In any case the rack has to be protected by a 10 A breaker (powered by 230 V AC) or 25 A (powered by -48 V DC).

The following figure shows the power supply configuration if the power distribution panel is used.

Figure 8 Ground-and power supply connections (example)

A 3 pole IEC 320 plug is located at the bottom of the rack for the 230 V AC mains input.

For connecting the BS 20 rack with the AC mains connection point proceed in steps as follows: Check the actual distance between rack and mains connection point or power dis-

tribution panel (if required). Cut the cable for the required length. Fix the socket at the end, which has to be connected at the mains input (Fig.2.8). Lead the main cable to the connection point for 230 V AC.

2.7.3 48 V DC - External EquipmentTo provide for function of external equipment (e.g. microwave, network termination) the 48 V DC output located at the bottom of the rack could be used.

A cable (2x4mm) is required for connecting the 48 V DC output with these equipment parts.

Depending on the site-specific 48 V DC power supply configuration, the rack has to be connected directly with the external equipment or a (optional) power distribution panel is used.

A splash-proof 2 pole socket is located at the bottom of the rack for the 48 V DC output.

Connect the BS 20 rack with the external equipment in the following steps: Check the actual distance between rack and the installation points of the equipment. Cut the cable to the required length. Fix the CA-CON plug at the end to be connected with the 48 V DC output. Pay atten-

tion to the assembly instructions of the plug and the handling instructions of the cable which has to be used.

Remove the screw cap of the socket. Insert the plug and tighten the screw cap. Lead the cable to the connection point of external equipment.

Note that the types of external equipment are subject to modification. A description of the connection is not part of this manual. For further information refer to the site-specific documentation and use those parts corresponding to the infrastructure equipment.

Figure 11 Pinning of the DC for external equipment interface

2.7.4 Connection of the External Backup BatteryTo extend the backup time in case of AC failure, the BS 20 rack could be powered by external batteries. A splash-proof 2 pole socket is located at the bottom of the rack for connect these batteries.

Prior to starting the installation works, consult the site documentation to locate the instal-lation point of the external batteries.

Connect the BS 20 rack with the external backup batteries in the following steps: Check the distance between the socket "DC for ext. battery" and the connection

point of the battery pack. Cut the cable (e.g. H07RN-F-2x6 mm) to the required length.

Remove the screw cap of the socket. Insert the plug and tighten his screw cap. Lead the cable to the connection point of the battery pack.

Note that types of battery and their connecting are subject to modification. For further information refer to the site-specific documentation and use the corresponding docu-mentation of the manufacturer.

Figure 12 Pinning of external battery connector

For connection of the AC/DC converter with the external backup batteries, the uncon-nected wires of the DC/Alarm cable are used.

Insert the prepared ends into the terminal block, located on the left side inside the rack.

Pay attention to the correct polarity: "+" wire red; "-" wire blue Tighten the clamping screws.

2.7.5 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).

Dependent 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. MOD-IY-2DY-FCY. Use coaxial cables for 75 Ohm wiring, e.g. S-09YS(ST)CY 8x2x0.6/1.2.

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).

2.7.5.1 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. Insert the additional wire (shielding potential) into one of the ground terminals (e.g.

no. 24). Lead the additional wire and the uplink and downlink wires on the shortest way (that

means without sleeves) between the stress relieving and the screw terminals. All unconnected PCM lines (4 wires per line) must be connected to one of the

ground terminals.

It is advantageous to protect the short part of the cable between stress relieving and terminal block with a shrink tube or adhesive tape.

2.10.2 Identification of Antenna Feeder CablesFor installation 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.

Adhesive tape in different colours will be used for identification of the antenna feeder cables, which has to be connected via short jumper cables to the antenna connectors of the BS20.
