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. 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 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 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. 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. Ports Safety Status V.11, V.28, V.35, V.36, RS-530, X.21, 10 BaseT, 100 BaseT, Unbalanced E1, E2, E3, STM, DS-2, DS-3, S-Interface ISDN, Analog voice E&M SELV Safety Extra Low Voltage: Ports which do not present a safety hazard. Usually up to 30 VAC or 60 VDC. xDSL (without feeding voltage), Balanced E1, T1, Sub E1/T1 TNV-1 Telecommunication Network Voltage-1: Ports whose normal operating voltage is within the limits of SELV, on which overvoltages from telecommunications networks are possible. FXS (Foreign Exchange Subscriber) TNV-2 Telecommunication Network Voltage-2: 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 not possible. These ports are not permitted to be directly connected to external telephone and data lines. FXO (Foreign Exchange Office), xDSL (with feeding voltage), U-Interface ISDN 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. 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. Note
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 CautionAttention
cables) to sensitive data lines. Before connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist strap.
