Preface 0.1. Safety Instructions 1) Grounding:The access unit and extension unit of the device are equipped with protective grounding terminals. During installation, yellow-green grounding wires should be used to ensure a reliable connection to the building’s protective earth. Grounding braided straps may also be used. The antenna and feeder cables must be properly grounded. 2) Power Supply:The device supports DC 48V power supply or AC 220V (198–240V) power supply. Please ensure that the DC power source is within the device’s required range of DC 36–60V. The grounding terminal of the device must be reliably connected to the building’s protective earth. 3) Electric Shock Protection:Touching the internal power module of the device is dangerous. Live operation is strictly prohibited to prevent electric shock.。 4) Optical Module:The optical module supports hot-swapping, but the fiber optic connector must not be pointed at any part of the human body during insertion or removal. 5) Surge Protection: The built-in surge protector of this product is mainly designed to protect against induced lightning and switching overvoltage. It cannot protect against direct lightning strikes. • In areas with frequent lightning activity, it is recommended to install a primary surge protector (10/350 μs waveform) at the building’s main distribution panel, and a secondary surge protector (8/20 μs waveform) at the distribution cabinet or in front of the device to form a layered protection system. • The surge protection components are single-use devices and may fail after exposure to high-energy lightning strikes. Regular inspection is recommended, especially after lightning events. • If the device is installed in open or elevated locations (such as rooftops), additional external lightning protection measures (e.g., lightning rods) must be implemented. 0.2. Warning Marks The warning labels on the system enclosure and within the system must be kept clean, legible, and clearly identifiable. 0.3. Electrostatic Protection 1. Avoid allowing clothing or hands to come into contact with PCBs, electronic components, and conductive surfaces of parts whenever possible. If handling of PCBs, components, or conductive parts is necessary, proper anti-static precautions must be taken, such as wearing anti-static gloves or using anti-static bags. Electrostatic discharge (ESD) may damage the equipment. 1.1. Standard Protection rating complies with IP67. RF performance complies with 3GPP standards. 4…
