6.3.1. MAST/POLE INSTALLATION
The different section types of mast/pole where the MBS Unit can be mounted are the
following ones:
Circular section: Diameter from 30 mm to 130 mm.
Square section: From 30 mm x30 mm to 85 mm x85 mm.
L section: From 30 mm x30 mm to 110 mm x110 mm.
In the choice of the mast/pole where the MBS Unit is being installed the following
recommendations must be followed:
The mast/pole has to support the loads due to the installation of some elements
on them.
The mast/pole has to support the loads due to the action of the wind, snow as
well as its own weight, because these are going to induce its flexion.
The mast/pole must have the enough inertia both lateral and frontal in order that
the action of different loads does not induce permanent deformations on it.
The manufacturer of the mast/pole must evaluate the structural factor of the
mast/pole correctly depending on its type.
It is necessary to take into account both the height where the MBS Unit is
installed and its weight/dimensions (See section “MBS Unit” in chapter
(F067326) “SBS Technical Description” in the Technical Manual).
It is recommended to choose a lattice mast/pole in case of this one has a
high height and it is going to be submitted to important flexion efforts. In any
case, it is responsibility of the manufacturer of the mast/pole to determine if
the resistant section of mast/pole is suitable.

MANUAL Date: 05/10/11 Page: 18 of 38
01.01.00/1 Rev.1
The brackets should be installed tight enough to support the MBS Unit without causing
deformation of the mast/pole or areas of corrosion.
Once mounted in its definitive location, if the vandal resistant kit is available, it will
prevent the access / disassembly not authorized.
In case of installing more than one MBS Unit on the same mast/pole, it is recommended
not to mount one above the other one to avoid the heat transfer from the MBS Unit low
to the MBS Unit high. If the MBS Units have to be installed in the same vertical axis
these must be oriented in different directions to increase the separation of them as far as
possible, depending on the length of wiring between both equipments (1.5 m
approximately).

Steps to install a MBS on a mast/pole:
1) Place the MBS Unit bracket on the mast/pole as follows.
Note: Handle the MBS Unit bracket with care if it rests on the floor. Place some
protection underneath to prevent scratches on the surface.
a) Secure 4 holes clamps on the bracket by tightening the bolts with a 15 Nm
torque, using a 17 mm torque wrench, do not forget to place the washers
b) Install the bracket to the desired final location on the mast/pole. Embrace the 2

c) In both cases:
The power supply cable to the MBS Unit must be provided by the installer
with the proper power supply connector adapted for the connection to the
electrical network or to a 24 VDC source
Ensure that the earth connection is made. The MBS Unit has an earth
connector; this connector will connect to the earth protection of the
installation, which is different to the earth protection of the lightning rod.
Make this connection with a cable of, at least, 25 mm2 section (or AWG-3).
NEVER use a gas or electricity conduit as an earth.
6.3.4.3. ANTENNA CONNECTION
With every MBS Unit, a RF super-flexible wire, N-Male – N-Male, is supplied
to connect the ANT connector of the MBS Unit with the RF wire of the
antenna.
Note: In case of installation a MBS Unit with diversity 2, it is recommended to
contact your supplier and/or installer who will provide the additional RF
super-flexible wire (Cod. 208931).
The RF assembly depends on the cable type used in the installation up to the
antenna.
The RF cable must have a protection against water entry (vulcanizable tape).
Choose the most adaptable antenna for the installation. The antenna must
have an impedance of 50 ohms to the equipment transmission frequency.
Install the antenna in accordance with the manufacturer’s instructions.
Use a coaxial cable, avoiding as much as possible large cable lengths. Cable
impedance is 50 ohms.

In installations with diversity, the greatest gain is achieved by placing the
antennas on the same horizontal plane with a minimum distance of 5.5 m
between them.
Measure the ROE of the installation. Never accept a ROE greater than 2.
6.3.4.4. EXTERNAL ETHERNET CONNECTION
The Ethernet cable connector, to connect the MBS Unit with the radio link
(PoE), is supplied with every MBS Unit.
Note: In the case of connection to two radio links, it is recommended to
contact your supplier and/or installer who will provide the additional Ethernet
cable connector.
The Ethernet wire for the radio link connections is supplied by the installer,
and must have the following characteristics:
Cable with 8 wires, FTP cat5E with outdoor protection.
Diameter: 6.5 mm to 9.5 mm.
Maximum length: 100 m
Mount the wire on the connector according to the TIA / EIA 568B

6.3.4.5. CONNECTION BETWEEN TWO MBS UNITS
To connect two MBS Units you must have the interconnection kit for additional carrier
(Cod. D014001). This is obtained as an independent accessory.
Apart from the power wiring, antennas and radio links to connect as indicated in the
section of supported configurations, it should be considered the use of interconnection
kit between the two Units MBS, as indicated bellow.

7. START UP/CONFIGURATION/VERIFICATION
IMPORTANT: Ensure that the power supply of the MBS Unit is the proper
one before switch it on; an erroneous power supply can cause damages in
the equipment.
Every MBS Unit has in its labelling the diverse options that it offers. If the
MBS Unit includes the option O148017, this it will have to be powered with
AC (220/110 VAC), however, if the MBS Unit includes the option O148018 it
will have to be powerred with +24 VDC nominal voltage.
Preliminary considerations for carrying out the MBS Unit start up:
• To start up the equipment, this must have the final IP correctly configured (see
chapter of infrastructure configuration (F067220) in the Technical Manual).
• Refer to the radio link used to configure this device. Make sure this element is
properly connected to ground.
The steps to perform the final settings are:
1. Before connecting power supply to the MBS Unit, make sure the right voltage level
reaches the power supply cable connector.
2. Provide power to the MBS Units through the POWER_IN connector.
3. Wait for the MBS Unit initialization (about 3 minutes).
4.
Verify that you have access to the MBS (by performing a "ping"). Make partial checks in
case of no response from the MBS, perform pings to intermediate elements: SNI Æ Node
radio link Æ remote site radio link Æ MBS.
5. From NMS, register the MBS Unit(s), completing the necessary settings (see chapter of
infrastructure configuration, F067220, and the client's user manual NMS, F067201).
6.
Verify the absence of alarms in monitoring module and check with a radio terminal that it is
registered and you can make and receive calls. In case of interference or coverage fault
alarms see chapter of the infrastructure adjustment (F067218).

8. INCIDENTS
The MBS Unit must be repaired by authorized technical personnel only. There
will not be performed any repair of the MBS Unit and it will have to be sent to
factory except for the change of the pressure equalizer or the overvoltage
protections.
8.1. INTERFERENCE AT MBS UNIT
This alarm is monitored in the NEBULA (NMS) management and configuration module.
See the infrastructure event list (F067516) in NEBULA Technical Manual.
Any interference in the MBS Unit is activated when there are a large number of
consecutive invalid events in the MBS Unit. A reception fault is considered when a level
higher than the threshold for reception of the carrier, but is not recognized as a valid
signal. Depending on the signal level, interference is considered low or high. So, if the
level of signal is above the threshold for reception and below the threshold set to high
interference and is not recognized as a valid sign, it will be a low interference alarm. If the
signal level is above the threshold set to high interference and is not recognized as a valid
signal, the low level alarm would disappear (if it happened) and high interference would
produce.
These alarms are turned off with any valid signal reception for low interference case, and
with more than one consecutive right reception for high-level interference.
8.2. OVER VOLTAGE PROTECTION
The MBS Unit has several protections against lightning and surges, in any case the action
of these protections generate an alarm in the NMS client which disappear when the
protective element is replaced by authorized technical staff.
a) Protection against lightning and power surges
This protection is located within the MBS Unit. It should be changed every time it
breaks even if the MBS Unit continues functioning properly. An alarm in the NMS
Client is reported showing that the replacement of this type of protection is needed.
b) Protection against lightning and surges in the RF connections
This protection is located inside the connectors themselves (ANT and DIV_IN).
These connectors have a gas discharger that when it is broken, it ceases to
receive/transmit signal through the connector. The NMS Client provides a reflected
alarm when the ANT discharger fails and diversity alarm when the DIV_IN
discharger fails.
