Issue Draft A (2014-10-31) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 38 RRU3269 Installation Guide 7 Installing RRU Cables l If DC power cables need to be routed close to a device on the tower, secure the cables to the guardrail or pole with cable clips. The device cannot be far away from the position for securing the cables. Cabling Requirements for PGND Cables l PGND cables for the base station must be connected to the same ground bar. l PGND cables must be buried in the ground or routed indoors. They should not be routed overhead before they are led into the equipment room. l The exterior of the coaxial wire and the shield layer of the shielded cable must have proper electrical contact with the metal surface of the equipment to which they are connected. l PGND cables and signal cables must be installed in an untangled and orderly fashion. A certain distance must be reserved between them to prevent interference from each other. l Fuses or switches must not be installed on the PGND cables. l Other devices must not be used for electrical connections of the PGND cables. l All the metal parts in the housing of the equipment must be reliably connected to the ground terminal. Cabling Requirements for E1 Cables l E1 cables must not cross power cables, PGND cables, or RF cables when routed. If transmission cables are routed with power cables, PGND cables, or RF cables in parallel, the spacing between them must be greater than 30 mm (1.18 in.). l E1 cables are routed straightly and bound neatly with cable ties. l Sufficient slack is provided in E1 cables at turns. l E1 cables cannot be squeezed by the cabinet door when routed through the cabinet, as shown in Figure 7-3. Figure 7-3 E1 cables routed through the cabinet Cabling Requirements for Fiber Optic Cables l Fiber optic cables must be routed by at least three qualified and trained personnel before all preparations are made. l Fiber optic cables are used within the temperature range of -40C to 60C. If the current temperature is out of the range, make protection measures or route the cables again. l Cables are routed in an untangled and orderly fashion. Issue Draft A (2014-10-31) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 39 RRU3269 Installation Guide 7 Installing RRU Cables l Do not bind fiber optic cables at turns. l Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables away from sharp objects. l When fiber optic cables are routed, the excess of the cables must be coiled around special devices, such as a fiber coiler. l An unarmored fiber optic cable must be bound using binding straps. If a fiber optic patch cord needs to be secured in a cabinet or a piece of equipment, use binding straps to bind it and then use cable ties to secure the binding straps to the cabinet or equipment. Ensure that the fiber optic cables can flexibly move in the cable ties. Do not bend the fiber optic cables sharply. The following figure shows how to bind the fiber optic cables correctly. Figure 7-4 Binding fiber optic cables l When coiling fiber optic cables, apply even strength. Do not bend the cables with force. l Vacant optical connectors must be covered with dustproof caps. l Fiber optic cables cannot be squeezed by the cabinet door when routed through the cabinet, as shown in Figure 7-5, Figure 7-6 and Figure 7-7.

Before installing or maintaining an antenna on a steel tower or a mast with a large number of transmitter antennas, coordinate with the parties concerned to shut down the transmitter antennas. Laser The laser hazard level of this device is Class 1. Issue (02) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 1-5 1 Safety When handling optical fibers, do not stand close to or look at the optical fiber outlet directly with unprotected eyes. General Laser Information Laser transceivers or transmitters are used in optical transmission systems and associated test tools. The wavelength of the laser is between 780 nm and 1600 nm. The laser transmitted through optical fibers has very high power density and is invisible to human eyes. A beam of light causes damage to the retina. Laser of wavelengths used in telecommunications causes thermal damage to the retina. Lasers used in lightwave systems have a larger beam divergence, typically 10 to 20 degrees. Looking at an un-terminated fiber or damaged fiber with unprotected eyes at a distance greater than 150 mm (6 inches) does not cause eye injury. Eye injury, however, may be caused if an optical tool such as a microscope, magnifying glass, or eye loupe is used to view the energized fiber end. A lightwave system in normal operating mode is totally enclosed and presents no risk of eye injury. The automatic laser shutdown (ALS) feature of the lightwave system also ensures safety. The ALS, however, can be applied to bi-directional transmission only. If the receiver side does not detect the laser from the transmitter side, it sends the transmitter side a signal. Upon receiving the signal, the ALS shuts down the laser emission within 100 ms. Safety Guidelines Follow the following guidelines to avoid laser radiation:
Read the instructions before installing, operating, and maintaining the device. Ignoring the instructions can cause exposure to dangerous laser radiation. Wear a pair of eye-protective glasses when you are handling lasers or fibers. Only qualified personnel are allowed to perform laser-related operations. Make sure that the optical source is switched off before disconnecting optical fiber connectors. Before opening the front door of an optical transmission system, make sure that you are not exposed to laser radiation. Do not look at the end of an exposed fiber or an open connector when you are not sure whether the optical source is switched off or not. Use an optical power meter to check that the optical source is switched off and verify that it is off by measuring the optical power. Do not use an optical tool such as a microscope, a magnifying glass, or an eye loupe to view the optical connector or fiber. Handling Fibers Read the instructions before handling fibers:
Only trained and qualified personnel can cut or splice fibers. 1-6 Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. Issue (02) Before cutting or splicing a fiber, ensure that the fiber is disconnected from the optical source. After disconnecting the fiber, use protecting caps to protect all the optical connectors. 1 Safety 1.1.5 Working at Heights Avoid object falling when you work at heights. When working at heights, fulfill the following requirements:
Only trained personnel can work at heights. Prevent the devices and tools that you carry from falling down. Take safety and protection measures, for example, wear a helm and safety belt. Wear warm clothes when working at heights in a cold region. Before working at heights, check that all the lifting facilities are in good condition. Hoisting Heavy Objects Do not walk below the cantilever or hoisted objects when heavy objects are being hoisted. Only trained and qualified personnel can perform hoisting operations. Before hoisting heavy objects, check that the hoisting tools are complete and in good condition. Before hoisting heavy objects, ensure that the hoisting tools are fixed to a secure object or wall with good weight capacity. Issue orders with short and explicit words to avoid misoperations. Ensure that the angle formed by two cables is not larger than 90 degrees. See Figure 1-1. Issue (02) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 1-7 1 Safety Figure 1-1 Hoisting heavy objects Using Ladders Checking a Ladder Before using a ladder, check whether the ladder is damaged. Only the ladder in good condition can be used. Before using a ladder, you should know the maximum weight capacity of the ladder. Avoid overweighing the ladder. Placing a Ladder The recommended gradient of ladders is 75 degrees. You can measure the gradient of the ladder with an angle square or your arms. When using a ladder, ensure that the wider feet of the ladder are downward, or take protection measures for the ladder feet to prevent the ladder from sliding. Ensure that the ladder is placed securely. Climbing Up a Ladder When climbing up a ladder, note the following:
Ensure that the center of gravity of your body does not deviate from the edges of the two long sides. To minimize the risk of falling, hold your balance on the ladder before any operation. 1-8 Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. Issue (02) 1 Safety Do not climb higher than the fourth rung of the ladder (counted from up to down). If you want to climb up a roof, ensure that the ladder top is at least one meter higher than the roof. 1.1.6 Mechanical Safety Drilling Holes Do not drill the cabinet at will. Drilling holes without complying with the requirements affects the electromagnetic shielding performance of the cabinet and damages the cables inside the cabinet. In addition, if the scraps caused by drilling enter the cabinet, the printed circuit boards (PCBs) may be short circuited. Before you drill a hole in the cabinet, wear insulated gloves and remove the internal cables from the cabinet. Wear an eye protector when drilling holes. This is to prevent your eyes from being injured by the splashing metal scraps. Ensure that the scraps caused by drilling do not enter the cabinet. Drilling holes without complying with the requirements affects the electromagnetic shielding performance of the cabinet. After drilling, clean the metal scraps immediately. Sharp Objects Before you hold or carry a device, wear protective gloves to avoid getting injured by sharp edges of the device. Lifting Heavy Objects When heavy objects are being lifted, do not stand or walk under the cantilever or the lifted object. 1.1.7 Bundling Signal Cables Issue (02) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 1-9 1 Safety Do not bundle signal cables with high current cables or high voltage cables.

To prevent damage to the device during lightning, ground the device properly. High Electrical Leakage If the "high electrical leakage" tag is present on the power terminal of the device, you must ground the device before powering it on. Fuse If a fuse is to be replaced, the new fuse must be of the same type and specifications. 1-10 Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. Issue (02) 1.2.2 Electrostatic Discharge 1 Safety The static electricity generated by human bodies may damage the electrostatic-sensitive components on boards, for example, the large-scale integrated (LSI) circuits. Human body movement, friction between human bodies and clothes, friction between shoes and floors, or handling of plastic articles causes static electromagnetic fields on human bodies. These static electromagnetic fields cannot be eliminated until the static is discharged. To prevent electrostatic-sensitive components from being damaged by the static on human bodies, you must wear a well-grounded ESD wrist strap when touching the device or handling boards or application-specific integrated circuits (ASICs). Figure 1-2 shows how to wear an ESD wrist strap. Figure 1-2 Wearing an ESD wrist strap 1.2.3 Installing and Removing a Board When installing a board, use proper force to prevent the pins on the backplane from being leaned. When installing or removing a board, note the following:
Insert the board along the guide rails. Prevent the surface of a board from contacting the surface of another board. This is to prevent the boards from being short-circuited or scratched. Issue (02) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 1-11 1 Safety To prevent electrostatic-sensitive devices from being damaged by the ESD, do not touch the circuits, components, connectors, or connection slots on boards. 1.2.4 Laying Cables When the temperature is very low, violent strike or vibration may damage the cable sheathing. To ensure safety, comply with the following requirements:
Cables can be laid or installed only when the temperature is higher than 0. Before laying cables which have been stored in a temperature lower than 0, move the cables to an environment of the ambient temperature and store them at the ambient temperature for at least 24 hours. Handle cables with caution, especially at a low temperature. Do not drop the cables directly from the vehicle. 1.3 Electromagnetic Field Exposure Introduction The Base Transceiver Station (BTS) emits Radio Frequency (RF) radiation. Follow the local safety regulations when installing and operating the BTS to avoid radiation hazard. Guidelines on Limiting Exposure to Electromagnetic Fields There are a number of international regulations, standards, and guidelines for exposure to electromagnetic fields. Some European countries have adopted the recommendation of the council of the European Union (1999/519/EC), released on July 12, 1999, focusing on the hazards of exposure to electromagnetic fields. The recommendation is based on the guideline published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Location of Base Station Antennas Base station antennas, the source of the radiation, are usually mounted:
On freestanding towers, with a height up to 30 m On a tower on the top of buildings To the side of buildings, on rare occasions Generally, the antenna cannot be located in a position lower than 10 m. The energy usually forms a horizontal main beam and is slightly tilted downwards. The remaining energy forms into weaker beams on both sides of the main beam. The main beam, however, does not reach the ground if the antenna is around 50200 m away from the ground. The highest level of emission would be expected in close vicinity of the antenna and in line of sight to the antenna. Exclusion Zones The requirements for exclusion zones are as follows:
The antenna should be properly located to prevent the public from accessing the area where the RF radiation exceeds the previously mentioned limits. 1-12 Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. Issue (02) If areas with excessive RF radiation are accessible to the operation and maintenance
(O&M) personnel, ensure that they know the source of radiation and can power off or shut down the transmitters before entering high radiation areas. In addition, such areas must be confined within a distance of 10 m from the antennas. Each exclusion zone should be defined by a physical barrier and by a recognizable sign warning the public or O&M personnel. 1 Safety Guidelines on Choosing Antenna Sites The guidelines on choosing the antenna sites are as follows:
For roof-mounted antennas, raise the antennas above the height of the personnel who may have to work on the rooftop. For roof-mounted antennas, keep the transmitter antennas away from the areas accessible to the public, such as roof access points, telephone service points, and HVAC devices. For roof-mounted directional antennas, place the antennas near the periphery, and do not make the antennas face the building. Consider the trade-off between large aperture antennas (lower maximum RF) and small aperture antennas (lower visual impact). Keep higher-power antennas away from accessible areas. Keep the antennas in a site that is far away from urban areas, though this may contradict the coverage area requirements. Exercise extra caution when designing co-location sites, that is, antennas owned by different companies are located in the same site or are co-sited. This applies particularly to sites that include high-power broadcast (FM/TV) antennas. Local zone often favors co-location, but co-location may cause safety problems. Take special precautions for antenna sites near hospital and schools. Location of BTS The BTS is shielded from RF radiation hazards. The device has been tested to comply with the radioactive spurious emission requirements of international standards or local regulations. Therefore, the BTS under normal operating conditions does not cause danger to the public and O&M engineers. However, the limits for RF radiation might be exceeded due to faulty antenna cables or for other causes. BTS sites shall not be accessible to the public. Only authorized and trained personnel can access BTS sites or equipment rooms. A sign of excessive RF radiation must be present on the doors of the sites or equipment rooms to warn the personnel inside the site or equipment room of excessive RF radiation. BTS sites must be regularly monitored and inspected after installation. Prediction of the Exposure to Electromagnetic Fields This section provides a theoretical approach to calculate possible exposure to electromagnetic radiation around a BTS antenna. Precise statements are possible either with measurements or complex calculations considering the complexity of the environment, such as soil conditions, nearby buildings and other obstacles. The complexity may cause reflection, deflection, and scattering of electromagnetic fields. The maximum output power (given in EIRP) of a BTS is usually limited by license conditions of the network operator. Issue (02) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 1-13 1 Safety A rough estimation of the expected exposure in power flux density on a given point can be made with the following equation:
S = (P(W) x Gnumeric)/(4 x r(m) x ) Where, P = Maximum output power at antenna port of the BTS in W Gnumeric = Numeric gain (see below) r = Distance between the antenna and the point of exposure in meters For the calculation of the Gnumeric, Gnumeric = 10GdB/10 GdB = Gantenna(dB) Bcable(dB) Bvertical-attenutation(dB) Bhorizontal-attenuation(dB) B = attenuation in dB Maximum antenna gain 17dBi use the RRU 1-14 Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd.
