Warning
Handling Energized Products
General Safety Practices
Do not touch or tamper with the power supply when the power cord is connected. Line voltages may
be present inside certain products even when the power switch (if installed) is in the OFF position or a
fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous,
energy hazards may still exist.
Before working on equipment connected to power lines or telecommunication lines, remove jewelry
or any other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is
provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug
is provided on the product, it should be connected to the protective earth at all times, by a wire with a
diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks
and cabinets.
Always make the ground connection first and disconnect it last. Do not connect telecommunication
cables to ungrounded equipment. Make sure that all other cables are disconnected before
disconnecting the ground.
Connection of AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Always connect the power cord first to the equipment and then to the wall socket. If a power switch is
provided in the equipment, set it to the OFF position. If the power cord cannot be readily
disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency
switch is installed in the building installation.
Connection of DC Mains
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the
ground. Any single pole can be externally grounded.
Due to the high current capability of DC mains systems, care should be taken when connecting the DC
supply to avoid short-circuits and fire hazards.
DC units should be installed in a restricted access area, i.e. an area where access is authorized only to
qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source and that the installation
complies with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Before connecting the DC supply wires, ensure that power is removed form the DC circuit. Locate the
circuit breaker of the panel board that services the equipment and switch it to the OFF position. When
connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the
positive pole and last the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated in
the building installation.
Installing the Radio Terminals (RTs)
The following safety measures apply when installing the radio terminals and masts.
• Mast / pole / towers should comply with local standards such as BS6651.
• Only trained professional installers should be used when installing or dismantling radio terminals
and masts. The installer is responsible for meeting all building and safety codes.
• Before installing a terminal, make sure it is disconnected from power.
• A safety belt and climbing harness must be used when installing the radio terminals on a mast or
tower.
• Masts of height 3 meters or more must be guyed according to required industry standards and be
lightning protected.
• If a radio terminal is to be mounted at a height of more than 4 meters above the roof, it is
recommended that a climbable tower be installed to give access to the equipment and to prevent
antenna movement during strong winds.
• When installing equipment, beware of overhead high-voltage power lines. Never install a mast
under power lines.
• The mast structure must be grounded.
• Do not stand in front of live radio terminal.
• The installer should configure the output power level of antennas, according to country regulations
and per antenna type.
• The antenna used for this transmitter must be installed to provide a separation distance of at least
20 cm from all persons and must not be co-located or operating in conjunction with any other
antenna or transmitter.
Outdoor units and antennas should be installed ONLY by experienced
installation professionals who are familiar with local building and safety
codes and, wherever applicable, are licensed by the appropriate government
regulatory authorities. Failure to do so may void the AirMux-104/WinLink 582
warranty and may expose the end user or the service provider to legal and
financial liabilities. RAD, RADWIN and their resellers or distributors are not
liable for injury, damage or violation of regulations associated with the
installation of outdoor units or antennas.
Protection Against Lightning Activity
Observe the following safety measures to protect personnel and equipment:
• All outdoor equipment must be attached to a properly grounded structure, and installed masts
must be grounded, in order to provide protection against lightening, surges and static buildup. In
addition, mast over 3 meters should have lightning protection rod. Failure to do so creates a safety
risk and will void the equipment warranty.
• Do not work on the system or connect or disconnect the cables prior to, or during, electrical storm
activity.
• In case of an electrical storm, do not touch any outdoor electrical equipment and get off the roof
as quickly as possible.
Warning
Connection of Data and Telecommunications Cables
Data and telecommunication interfaces are classified according to their safety status.
The following table lists the status of several standard interfaces. If the status of a given port differs from
the standard one, a notice will be given in the manual.

telecommunication networks are possible.
The signals between the RT and RTCB are TNV-1.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a
qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables. Do
not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The
earthing and bonding of the ground connections should comply with the local codes.
The telecommunication wiring in the building may be damaged or present a fire hazard in case of
contact between exposed external wires and the AC power lines. In order to reduce the risk, there are
restrictions on the diameter of wires in the telecom cables, between the equipment and the mating
connectors.
Note
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de
télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such
cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of major
regulatory bodies. The following instructions may enhance the performance of the equipment and will
provide better protection against excessive emission and better immunity against disturbances.
A good earth connection is essential. When installing the equipment in a rack, make sure to remove all
traces of paint from the mounting points. Use suitable lock-washers and torque. If an external
grounding lug is provided, connect it to the earth bus using braided wire as short as possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for
high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on
certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines is
dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss
(LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary
protection against surges on the data lines. Primary protectors should be provided in the building
installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with plastic
connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before
connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist
strap.

2.2 AirMux-104 System
AirMux-104 system comprises the following units:
• Radio Terminal (RT): An enclosed aluminum frame with a front sealed plastic
cover, containing an integrated transceiver with an antenna, RF module,
modem and standard interfaces. The RT stores all configuration parameters of
the AirMux-104 system.
RT includes 16-pin KRONE-type connector which receives -48 VDC, E1 and
Ethernet traffic from the indoor unit (RTCB).
The RT is attached to a mast or a wall using a special mounting kit. The RT
mounting kit is supplied with the unit.
• Radio Terminal Connection Box (RTCB): The unit that interfaces between
the RT and the users. It converts 220 VAC to -48VDC, and sends it on to the
RT. The RTCB also splits the incoming data from the RT cable into two
separate lines, one for E1 and one for IP. The RTCB does not store any
configuration data, that is why when replacing an RTCB, there is no need for
additional configuration of the AirMux-104 system.
2.3 Installing AirMux-104 Management Software
AirMux-104 management application is distributed on CD-ROM as an executable
file. The application can be run under Windows 98/2000/NT/XP operating
system.

Mounting and Aligning the RT
The RT is the transmitting and receiving element of the AirMux-104 system. The
RT can be mounted on a mast or a wall. In both installation types, the supplied
mounting kit is used to secure the RT. Appendix B describes the mast/wall
installation instructions.
You can verify that the AirMux-104 units are aligned using the RSS/SNR, LINK and
STATUS LEDs located at the base of the RT. Alternatively, this can be done via the
AirMux management software.
Prior to connecting cables to the RT, the protective earth terminal (screw) of
the RT must be connected to an external protective ground conductor or to a
grounded mast.
Only a qualified person using the proper safety equipment should climb the
antenna mast. Only trained professional installers should be used when
installing or dismantling RTs and masts.
