General Safety Instructions The following instructions serve as a general guide for the safe installation and operation of telecommunications products. Additional instructions, if applicable, are included inside the manual. Safety Symbols This symbol may appear on the equipment or in the text. It indicates potential safety hazards regarding product operation or maintenance Warning to operator or service personnel.
• Use of controls, adjustments or performing procedures other than those specified herein, may result in hazardous radiation 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.
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.
Outdoor units and antennas should be installed ONLY by experienced installation professionals who are familiar with local building and Warning 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.
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, SELV Unbalanced E1, E2, E3, STM, DS- Ports which do not present a safety hazard. Usually up to 30 VAC or 60 VDC.
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.
Caution To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords. Attention 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.
