1 General Design of Outdoor Units (ODU)
1.1 Application
The present document gives an overview of the technical characteristics of
AXR Outdoor Units (ODU) for the frequency range:
• 24.25 to 24.45 GHz paired with 25.05 to 25.25 GHz
In addition, it describes the installation of the Outdoor Units and the different
mounts and brackets required for this purpose.
1.2 Information on intended use
The radio unit may only be operated for the purposes defined in the operating
manual and within the parameters specified (such as transmit power,
transmission bit rate, frequency band, modulation procedure and safety
clearance from the antenna to avoid any damage to health from electromagnetic fields etc.).
Any change in the technical features and location may lead to the operating
permit becoming null and void.
Operation of the radio system is provided in many countries and is subject to
the operating conditions prevailing in each country. Operation is permitted only
with the approval of the authorities responsible for frequency management in
your country, in agreement with the operating regulations prevailing for a fixed
radio service in the frequency band (channel) intended. This permit must be
obtained prior to commissioning the system.
Note Only appropriately trained personnel may carry out installation and
operation work.

1.3 Safety instructions
Installation and maintenance work may only be carried out by personnel with
the required technical qualification and experience. The installation and
maintenance personnel must be aware of possible sources of danger and take
the necessary measures to reduce possible risks to a minimum.
1.3.1 Protective equipment
1.3.2 Voltage
1.3.3 Grounding
Protect yourself and passers-by against dangers!
When installing the Outdoor Units, the service personnel must use
appropriate safety equipment to prevent units or equipment
(particularly the Outdoor Unit, and mounting set) from falling down,
thus preventing damage to units and injury to service personnel and
passers-by.
The recommended protective equipment (helmet, gloves, safety belt
etc.) must be worn during the installation. Observe the national and
regional regulations and requirements.
CAUTION! Battery voltage!
The ODU is powered with the 48/60 V DC supply voltage via the inner
conductor of the system cable.
1.3.4 Lightning
Dangerous electrical voltage!
Improper grounding can apply dangerous electrical voltages to
housing parts!
Lightning!
You may only install the ODUs if the mast is grounded according to
regulations. Grounding must comply with the relevant regional
regulations.
Mounting work must not be carried out during or directly before
thunderstorms and must be stopped immediately the storm
commences.

1.3.5 Weight
Danger of injury!
The described units are very heavy. Handle them carefully and wear
suitable protective clothing (shoes).
1.3.6 Sources of Danger Through Microwaves
Danger due to electromagnetic radiation!
In order to avoid any hazards through electromagnetic radiation
caused by microwave radio Tx power, the transmitter must be
switched off before you start working at or near the antenna. If you
have to work for a longer period while transmission is active, please
stay only behind the antenna.
Possible hazards
Potential health hazards can occur due to exposure to electromagnetic fields if
the prescribed safety distances to the antenna are not observed in the main
beam direction and if the waveguide interfaces are opened while the Outdoor
Unit is on.
Protection measures
• If possible, switch the transmitter off before you disassemble the device or
waveguide interfaces.
• Do not look into open waveguide joints. Do not stand directly in front of
transmit antennas.
• Mind the prescribed safety distances in front of the antennas (specified
below).
• If the safety distances cannot be maintained, the power supply to the
antenna must be reduced or the transmitter switched off.

Warning:
Do not open waveguide joints without switching off the
transmitters. Electormagnetic fields can be harmful to the
body (particulary to the eyes) and can also cause rf-interference.
Permissible limiting values
In DIN VDE 0848 "Safety in Electromagnetic Fields", a distinction is made
between two exposure areas.

European Communities
(1999/519/EC)
Exposure Area 1 includes:
• Controlled areas, e.g. operating areas and areas that can be monitored by
the operator.
• Generally accessible areas where, on account of the method of system
operation or the time spent by persons in these areas, it may be assured
that exposure will occur for short periods of time only (up to 6 hours per
day).
Exposure Area 2 includes:
• Residential districts or areas where sports and recreational facilities are
located;

Version: DRAFT General Design of Outdoor Units (ODU)
• General areas where long-term exposure (more than 6 hours per day) is
expected.
A sign or other safety precautions, at the access to the antenna system (e.g.
skylight), is not required if it can be assured that unauthorized persons cannot
approach within the safety distance in front of the antennas.
If this cannot be assured, a suitable sign (No unauthorized entry!) must be
located at the access to the antennas.
In addition, the safety precautions stipulated by the site proprietor for access
and presence in the area of transmitter systems shall be observed.
Safety distances in the area in front of antennas
The evaluation in accordance with the "OET Bulletin 65" (F.C.C.) and with the
"Safety Code 6" (Industry Canada) is performed in separate documents, which
can be provided on request.
Safety distances are not required according to these evaluations.
