1.6 Safety Instructions

Persons other than the maintenance personnel must not touch the devices inside theAC-Distribution. The AC-Distribution involves a high voltage and high current. Touchingit can lead to an electrical shock or accident.

Make sure not to touch parts of the Node B that contains components with high voltageor current. An inadvertent contact with any of these components can cause injury, death,and/or damage to the system.

Be sure to provide grounding where required. A failure to do so can lead to a systemfailure or electrical shock at the time of lightning.

When measuring voltage or current, take adequate insulating measures, such as cov-ering or winding the superfluous parts of the measuring terminal and tools with insulatingtape. Allowing the measuring terminal to touch another terminal or a short-circuit causedby a tool can lead to an electrical shock or accident.

Before making a connection with the DC-PDB, ensure that the power to the main andbattery circuit breaker is OFF. Making a connection with the DC-PDB when the poweris ON can lead to an electrical shock or accident.

Before making a cable connection, be sure to turn the switch on the power distributionboard to OFF. Otherwise, an electrical shock or accident can result.

Before making a cable connection, confirm the electric polarity. If the cable is connectedwith wrong polarity, an electrical shock or accident can result.

2.3 Environmental ConditionsThe location of a site may directly effect the correct operation of the base station.

In areas of excessive salt contamination situations it is recommended not to place theNB-441 close to coastal areas in order to avoid shorter maintenance intervals.It is recommended to keep a distance of about > 1 mile from the coast.Enclosures on coastal sites should not be installed with the air intakes facing directly intoprevailing sea winds or spray.

Installation under trees and foliage is not recommended due to increased levels ofinsects etc. which may be drawn into the cooling system by the fans.

In areas of heavy snow fall the base station should be placed on a base constructionwith an appropriate height, so that the air intakes will not be blocked by snow.

In areas prone to flooding the base station should not be placed on the ground,because its bottom section is not waterproof.

Sites located close to excessive airborne dust clouds i.e. cement, coal deposits etc.should also be minimized in order to avoid contamination of the cooling system andincreased maintenance.

2.4 Site CongurationOperation of the NB-441 requires additional equipment on site:

Linear Power Amplier (LPA):The LPA is the RF power amplifier. An LPA is capable of supporting one or twocarriers (LPA-MCF).

Baseband Processing Modules: Channel Coding Card (CHC ):The main function of CHC is the channel coding and decoding procedure.CHC can simultaneously perform the channel coding and decoding procedure forboth traffic channel and control channel.

Repeater Card (REP ):The REP card provides a repeater function for base band signals. The cards sortsthe downlink signals from the CHC cards according to antennas and sends them tothe TRX cards. The card sends also the signals from the TRX cards to the CHCcards in uplink direction.

Transceiver Card (TRX):The TRX card has transceiver base band block (TRX BB) and radio frequency block(RF). The radio frequency block is composed of the transmitter block (TX) and thereceiver block (RX). Both TX and RX have diversity configuration. The transmitterblock converts baseband signals into RF signals and the receiver block converts RFsignals into base band signals.

Core Controller (CC ):The Core Controller accomplishes the signal transmission and data controlling of thebase section and manages the data transfer with the Radio Network Controller and theChannel Coding Cards.

Overvoltage Protection and Tracer (OVPT ):Protects the E1 ports of the Iub interface and the external synchronization clock input ofthe Node B from overvoltage and provides interfaces for connection of externalmonitoring equipment without interruption.

Additional accommodate the Base and the Extension section of Twin Shelter a MainsSupply Unit (MSU), a DC Panel, an Alarm Collection Terminal (ACT) as well FANs, Heat-er and Membrane Filter (MEF).

Tower Mounted Amplifier (TMAF):The TMAF (optional) is a RF unit (external to the Node B shelter) which provides themeans to feed the overall Node B downlink signal to one TX/RX antenna and to amplify,with low noise figure, the overall Node B uplink signal coming from the sameTX/RX antenna.

2.7.3 Iub-Interface - Iub Link TerminalThe Iub interfaces Iub0 and Iub1, located on EMI Panel, provides the communicationlinks to the neighboring Base Stations or to the controlling RNC.

The Iub interfaces are terminated with Overvoltage Protections (OVPT) which protectsthe boards inside the NB-441 against overvoltage (residual voltage < 1 kV) or theIUBCON, without overvoltage protection.Two types of OVPT exist: OVPTE1CF for 75 and OVPTE1J1SF for 100/110/120 lines. If the overvoltage protection function is not needed, the IUBCONSF will be usedfor 100/110/120 lines or the IUBCONCF for 75 coaxial lines.

Depending on the different cable impedances it is recommended to use: screened cable containing 8/10 shielded twisted pairs 0,25 mm for

100/110/120 Iub lines. (for T1 the cable with resistance 100 and for J1 the cablewith resistance 110 are necessary.)

coaxial cables for 75 wiring, e.g. 2YCCY 0.4/2.5.

The outer diameter of the Iub cable should be not exceed 8 mm.

The maximum cable length depends on the attenuation of the cable, in order to fulfillthe requirements of minimum voltage levels to be provided at Iub interface accordingto Iub standards. The cable shielding must be connected to the relevant ground pins asclose as possible (in order to avoid EMC / RF interfering effects).

2.7.3.1 Iub-Interface for 100/120 Ohm Cable Impedance

Before starting the connection of the Iub cables at the Iub interface of the OVPTE1J1SF,or the IUBCONSF prepare the cables as shown in the figure below.

Fig. 2.24 Preparation of the Iub-cable, 120 impedance

2.7.9 Installation of the Tower Mounted AmplifiersThe Tower Mounted Amplifiers ( TMAF or DTMAF) are the RF units (external to theNodeB shelter) which provides the means to feed the overall NodeB downlink signal to

one TX/RX antenna and to amplify, with low noise figure, the overall NodeB uplink signalcoming from the same TX/RX antenna.

The TMAF / DTMAF should be placed as close to the antenna as possible.It will be supplied and supervised by the multicoupling equipment (DUAMCOF) in theshelter it is connected to.

The DTMAF provides two 7/16 female connectors at the bottom for the connection withthe Node B (lettered NodeB 0 and NodeB 1) and on the top both 7/16 connectors forconnecting the jumper cables to the antennas (lettered ANT 0 and ANT 1).

Each TMAF / DTMAF shall be grounded to the pole, therefore a grounding wire has tobe prepared for each device on site.The mounting plate has a screw with a locking washer attached to it and a threaded holefor connection of the grounding wire (see Fig. 2.52 and Fig. 2.54 ).The grounding wire cable lug must have the right size for the M8 ground screw. Thecross section of the ground wire must be not less than 16 mm 2.

The other end of the grounding wire should be safely connected to a well grounded pointon the pole.

Care must be taken that the draining pipe (see Fig. 2.52 and Fig. 2.54 ) is pointed down-wards. The draining pipe is factory mounted. If it, for any reason, would be loosened, itshould be tightened again with a sufficient torque wrench, however not exceeding2.2 Nm.

The draining pipe must never be obstructed or covered with paint which would impedethe venting and draining of the housing.

2.7.9.1 Pole Mounting with Hose ClipsThe hose clips surrounds the pole and are fitted into the corresponding openings of themounting plate (see Fig. 2.57 ). This is the situation just before tightening the hose clips.

For the mounting, the following steps can be generallyrecommended. First connect theTMAF to the antenna feeder cable. Take into consideration that the antenna feeder oftenis very stiff and rather heavy. The position of its coaxial connectors therefore often de-termines the position of the TMAF on the pole.

1. Open the hose clips by pressing the button at the end of the clip lock and thensmoothly pull out the perforated metal band.

2. Move the metal band of the hose clip gently into the openings of the mounting plate.3. Close the hose clip loosely around the pole.4. Shift the TMAF into the correct mounting position.5. Tighten the hose clip screws carefully, but do not over-tighten (see Fig. 2.58 ).6. Connect the TMAF rst to the antenna feeder cable (NodeB) and then to the antenna

jumper cable (ANT). The tightening torque must be 25 - 30 Nm.7. Connect the grounding wire with the TMAF ground screw.

Check the tightening torque, 5 Nm.8. The use of self-vulcanizing tape as an environmental protection of the connectors

is recommended.

i NOTEThe TMAF and the DTMAF can be pole-or wall mounted in vertical position only !
