Any person involved in installation or service of the DAS should understand and follow these safety guidelines.” - Obey all general and regional installation and safety regulations relating to work on high voltage installations, as well as regulations covering correct use of tools and personal protective equipment. - The power supply unit in repeaters contains dangerous voltage level, which can cause electric shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when servicing repeaters. - eROU equipment is exclusive to the indoor. - Use this unit only for the purpose specified by the manufacturer. Do not carry out any modifications or fit any spare parts which are not sold or recommended by the manufacturer. This could cause fires, electric shock or other injuries. - Any DAS system or Fiber BDA will generate radio (RF) signals and continuously emit RF energy. Avoid prolonged exposure to the antennas. SOLiD recommends maintaining a 50 cm minimum clearance from the antenna while the system is operating. - Do not operate this unit on or close to flammable materials, as the unit may reach high temperatures due to power dissipation. - Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives on the DAS equipment. Alcohol may be used to clean fiber optic cabling ends and connectors. - To prevent electrical shock, switch the main power supply off prior to working with the DAS System or Fiber BDA. Never install or use electrical equipment in a wet location or during a lightning storm. - Do not look into the ends of any optical fiber or directly into the optical transceiver of any digital unit. Use an optical spectrum analyzer to verify active fibers. Place a protective cap over any radiating transceiver or optical fiber connector to avoid the potential of radiation exposure. - Allow sufficient fiber length to permit routing without severe bends. - For pluggable equipment, make sure to install the socket outlet near the equipment so that it is easily accessible. - A readily accessible disconnect device shall be incorporated external to the equipment. - This power of this system shall be supplied through wiring installed in a normal building. If powered directly from the mains distribution system, it shall be used additional protection, such as Confidential & Proprietary 6/19 overvoltage protection device - Only 50 ohm rated antennas, cables and passive equipment shall be used with this remote. Any equipment attached to this device not meeting this standard may cause degradation and unwanted signals in the bi-directional system. All components connected to this device must operate in the frequency range of this device. - Only 50 ohm rated antennas, cables and passive components operating from 150 - 3 GHz shall be used with this device. - The head end unit must always be connected to the Base Station using a direct cabled connection.
