Product Installation 4.1 Safety Information Before performing any operation, read the following precautions and operation instructions carefully to ward off potential risks. Regulations and Specifications Observe local regulations and specifications when installing the equipment. Power supply Danger Direct contact or indirect contact (through moist objects) with the high voltage or mains electricity may result in an electric shock. Nonstandard or incorrect operations may lead to accidents such as a fire or electric shock. Never wear conductive articles such as watches, bracelets or rings during operation. Do use dedicated tools during high voltage or AC operations. Take necessary measures to prevent entry of moisture into the device operating under a moist environment. Make sure the lightning-proof grounding is implemented for the device to prevent it from being damaged by lightning strikes. Disconnect the device from the power supply before installing or removing it. Check the cable and the label on it to ensure correct connection. Make sure that the device is well grounded before connecting it to the power supply. Disconnect the device from the power supply if you find water or other liquids in the device. Make sure the power switch is toggled to the "Off" position before installing the device. Working at Height Work at height refers to work performed at a height more than 2 m above the ground. Pay attention to the following items during the work at height. Stop the work at height in case of hazardous conditions such as thunder and lightning, rain, snow, gale above scale 6, and steel pipe with rainwater. Define a hazardous zone on the work site at height, set an obvious sign, and prevent unauthorized persons from entering the area. 7 User Guide Do not pile scaffolds, gangplanks or other sundries on the lower ground of the work area at height. Ground workers are not allowed to stay under the work area at height or pass through it. People who work at height should not throw objects to the ground from the high altitude or to the high altitude from the ground. Instead, they should use strong ropes, hanging baskets, overhead vehicles, or cranes to transport objects. Take sound safety actions such as wearing the hamlet and safety belt properly. Do wear heat-retaining clothes when working in cold areas. Make sure that the ladder is safe for use, and overload is strictly prohibited. People who work at height should handle and use all instruments and tools with care to avoid falling to injure others. Do not frolick when working at height or sleep in the work area at height. Personnel The person who performs equipment operations must have acquired the basic knowledge of safety operations, received professional training, and obtained the corresponding operation qualifications. 4.2 Installation Flow The figure below shows the RRU installation flow. 8 Pole-mounted installationStartSuspended installationInstallation and power-on checkEndInstall cablesInstallation preparations User Guide 4.3 Installation Preparations 4.3.1 Environment Requirements Space Requirements Keep a space of at least 200 mm above the RRU.

Insert the RRU backboard into the slot of the hanging part, and tighten the captive screws on the RRU backboard, as shown below. 4.5 Installing Cables 4.5.1 Cabling Requirements Lay cables according to the related cabling requirements to prevent inter-signal interference. Safety requirements Avoid sharp objects or wall burrs as laying out cables. Use bushings to protect cables when they cannot be avoided. Stay away from the heat source as laying out cables, or add thermal insulation materials between the cables and the heat source. Binding requirements Bind the cables of the same type together. 14 User Guide The bound cables should be kept close to each other and look straight and tidy, without sheath damage. The cable ties should face the same direction; the cable ties at the same position should be at the same level. After cables are installed, make sure to stick labels at two ends, intermediate connection positions, and turning points of cables. Lay out different types of cables separately. Prevent laid cables from twisting or crossing each other. Power cord laying requirements The power cord laying positions should comply with the engineering design drawing requirements. If the power cord length is not enough during laying, replace the power cord. Do not make joint or welding spot along the power cord. Avoid circling or twisting when laying the power cord. PGND cable laying requirements Do not lead in the PGND cable from the outdoor overhead layer. It must be buried underground in the whole course or routed indoors. Do not bind the PGND cable and signal wire together or make them intertwined, and keep a distance between them to avoid mutual interference. All the accessible conductive metal parts in the device enclosure must be connected to the protection ground terminal reliably. Fiber laying requirements Do not bind the fiber at the fiber bending position. Do not pull the fiber forcefully or use a foot or other heavy objects to press the fiber, and prevent the fiber from coming into contact with sharp objects, lest the fiber would be damaged. When routing optical fibers, wind excess fibers on a special device, e.g., a fiber reel. For the optical fiber jumper, the fiber must be bound with cable ties. If the fibers need to be fixed on a cabinet or device, use cable ties for the optical fiber. Ensure that the fibers can be pulled freely in the cable ties but cannot be bent to form a right angle. Use uniform force when winding fibers. Do not force to bend fibers lest they would be damaged. Be sure to put on a dust cap when the fiber connector is not in use. 15 User Guide 4.5.2 Cable Connection Diagram The figure below shows the RRU cable connection diagram. 4.5.3 Installing PGND Cable 1. Cut a proper length of cable to make a RRU PGND cable according to the actual routing path, and install an OT terminal at each end of the cable. The metal wire cannot be exposed when the PGND cable is prepared on the field, as shown below. 2. Connect the OT terminal of the RRU PGND cable to the grounding port at the RRU bottom, and the OT terminal at the other end to the external grounding bar. 3. Stick a label to the installed cables. 16 AntennaExternalGNSS orWi-Fi deviceExternalBBU12345671RF jumperPGND cablepower cordGNSS jumper or RF jumperMonitoring cableCPRI fiber lineFeed line234567power supplymonitoring device User Guide 4.5.4 Installing RF Jumper 1.
