exposure.

ATTENTION: The laser beam may be invisible!

Always observe standard safety precautions during installation, operation and
maintenance of this product. Only qualified and authorized service personnel should
carry out adjustment, maintenance or repairs to this product. No installation,
adjustment, maintenance or repairs should be performed by either the operator or the
user.

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. Rack­mounted 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 install or dismantle 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 a 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 200 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

Warning

appropriate government regulatory authorities. Failure to do so may
void the AirMux-200 warranty and may expose the end user or the
service provider to legal and financial liabilities. RAD and its 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 a 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
leave the roof as quickly as possible.

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.

TNV-3 Telecommunication Network Voltage-3:
Ports whose normal operating voltage

exceeds the limits of SELV (usually up to 120 VDC
or telephone ringing voltages), on which
overvoltages from telecommunication networks
are possible.

Note

The signals between the IDU and ODU 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.

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.
