5 Installing Nokia Indoor LMUThis chapter instructs how to install Nokia Indoor LMU. Tools and equipmentneeded in the installation are described in Requirements for Installation andOperation.

Installation, commissioning, and maintenance measures concerning Nokia IndoorLMU may be performed only by properly trained and authorised personnel.

Use an antistatic wrist strap when installing Nokia Indoor LMU.

5.1 Installing the mounting bracket

To install the mounting bracket:

1. Position the mounting bracket inside or on top of the BTS, or to a wall nearthe BTS. See Requirements for Installation and Operation for therecommended BTS-specific installation locations and required clearances.

2. Secure the mounting bracket to the mounting base. You can use threealternative fixing methods in BTS installation and one method in wallinstallation:


Installation

WARNING

Caution

Note

Before drilling any holes to the wall, ensure that there is no piping or electricwiring inside/behind it.

Do not drill any holes to the BTS cabinet.

Any of the mounting bracket holes can be used to secure it to the BTS cabinet orwall. Anchor plugs for wall mounting (if required) are customer-supplied.

a. With Nokia UltraSite GSM/EDGE BTSs, secure the mountingbracket from appropriate holes to the threaded holes on the BTScabinet with the shorter M4 TORX screws (see A of Figure 4).

b. With other BTSs, use the blind nuts and the longer M4 TORXscrews to fix the mounting bracket to larger holes (ø 8 - 9 mm/0.31- 0.35 in.) on the BTS cabinet.

Press the blind nuts through the holes on the BTS cabinet and securethe mounting bracket to the blind nuts with the TORX screws (see Bof Figure 4).

c. If the BTS cabinet does not have any holes where the mountingbracket fixing screws can be secured, use the two-sided tape tosecure the mounting bracket (see C of Figure 4). Clean the BTSmounting base before applying the tape.

d. If BTS installation is not possible or wall installation is preferred,install the mounting bracket to a wall. Depending on the wall type,use either the included self-tapping screws or other appropriatefixing screws to secure the mounting bracket (see D of Figure 4).

If using anchor plugs (or other appropriate counterparts), drill fourholes to the wall and insert the anchor plugs into the holes. Tightenthe upper and lower fixing screws to secure the mounting bracket.

5.2 Installing the LMU module

Ground the LMU module and the external AC/DC power supply’s cable (if used)before installing the LMU module to the mounting bracket (refer to Requirementsfor Installation and Operation).

If preferred, you can connect the cables to the LMU module before installing it tothe mounting bracket (see Chapter 6).

To install the LMU module to the mounting bracket:

If the external AC/DC power supply is used, install the LMU module in such away that the PWR/VDC connector on its side is left unobstructed.

1. Place one of the long edges of the LMU module under the longer side plateof the mounting bracket with the indicator LEDs facing up (see 1 of Figure5).

2. Press down the LMU module until it clicks into place between the sideplates of the mounting bracket (see 2 of Figure 5).



Note

Figure 5. Installing the LMU module to the mounting bracket

5.3 Installing the optional AC/DC power supply

Install the external AC/DC power supply to an easily accessible location - on orinside a pole or to a wall - in an upright position with the cables leavingdownwards. All fixing parts used in the installation are customer-supplied.

Nokia recommends wall mounting of the external AC/DC power supply becausethis requires the use of only four self-tapping screws. Select a screw type suitablefor the wall and check if anchor plugs are required (for example for concreteelement and brick walls). If pole mounting is used, you need a metal band and/orother additional fixing parts to secure the external AC/DC power supply.

When installed, the distance of the external AC/DC power supply from thegrounded socket-outlet must not exceed 1.5 m (4.9 ft.), and from Nokia IndoorLMU 5 m (16.4 ft.).

Securing of the external AC/DC power supply must meet the same vibration andearthquake requirements set for Nokia Indoor LMU (refer to Requirements forInstallation and Operation).

6.3 Cabling

6.3.1 Cabling with DE21/DF12/DG26 BTSs

To connect the cables with Mini Indoor cabinet (DE21 BTS) andSector Indoor cabinet (DE21/DF12 BTSs):

1.

a. Connect the feeder and jumper cables of the LMU GPS and LMUGSM RX antennas to the GPS and GSM EMP protectors (withfemale N-connectors) as shown in 1a of Figure 11.

b. If using internal GSM antenna, GSM EMP protector is not necessaryand the cable can be connected directly to the Cable Antenna asshown in 1b of Figure 11 or with an SMA-SMA jumper cable to thecombiner.

The grounding screws of the GPS and GSM EMP protectors should be fixed to agood grounding point - preferably the same point used for the BTS EMPprotectors.

2. Connect the jumper cables of the LMU GPS and LMU GSM RX antennasto the GPS and GSM connectors (SMA) on the LMU module (see 2 ofFigure 11). Use an SMA Torque wrench to tighten the SMA connectors to1.0 Nm (0.74 ft-lb).

3. Connect the BTS/Q1 LMU interface to the BTS/Q1 connector on the LMUmodule (see 2 of Figure 11). Tighten the fixing screws of BTS/Q1 interfaceD-connector by hand.

4. Connect the Q1 interface to a free Euroconnector slot (BCI) located on theBTS cabinet top (see 3 of Figure 11).

5. Connect the EACB cable (see 4 of Figure 12).

Connect the EACB1 interface to the EACB1/IN connector and theEACB2/Q1 interface to the EACB2/OUT connector on the EACB unit ofthe BTS.

Connect the Q1 interface to the opposite side of the LMU-BTS cable’s Q1interface on the Euroconnector slot.

6. Connect the fuse-link extensions and the PSU lines or the power supplycable.

If there is DC power available from the BTS, connect the fuse-linkextensions to the BTS’s terminal block and the PSU lines to the fuse-link’sterminal socket (see 5 of Figure 12).

The fuse-link must be used to prevent high current in case of faulty cabling orshort circuit caused by the installer.

The order of the fuse-link extensions in the BTS’s terminal block is not importantbecause Nokia Indoor LMU functions with both polarities.

7. Check the correct cabling from 6 in Figure 12.

8. If there is no DC power available from the BTS, connect the externalAC/DC power supply’s cable to the PWR/VDC connector on the LMUmodule (see 7 of Figure 12). Connect the other end of the cable to agrounded socket-outlet at the BTS site or use a grounded fixed mainsinstallation.

Fixed mains installation may be performed only by properly trained andauthorised personnel.

If using the external AC/DC power supply, leave the PSU lines of the LMU-BTSinterface cable unconnected and shield them with appropriate sleeves.

6.3.4 EXT Q1 cabling

Nokia Indoor LMU has an extra Q1 connector which allows chaining of Q1equipment to the same Q1 bus. Second synchronisation output signals are alsoavailable at this connector.

To connect another Q1 equipment:

• Connect the Q1 cable of the equipment (D9 connector) to the LMU’sexternal Q1 connector. Tighten the fixing screws of EXT/Q1 interface D-connector by hand.
