Do not throw batteries into fire, or it will cause fire and explosion 1.5 Radiation Safety 1.5.1 Electromagnetic Field Exposure This section describes safety precautions related to electromagnetic field exposure. Strong electromagnetic signals harm human health. If the equipment is a radio transmitter or product supporting radio transmission, exposure of radio electromagnetic field (electromagnetic radiation) should be considered. For the high-voltage equipment or facility, exposure of power frequency electromagnetic field should be considered. When professional equipment or facility (such as wireless base station transceiver) is deployed, the user (such as radio service carrier) must comply with local laws and regulations. Before the equipment structure or antenna is modified, re-evaluation of electromagnetic field exposure should be considered. Before the radio frequency (RF) output specifications or parameters are modified, reevaluation of electromagnetic field exposure should be considered. Safety Information Before the site environment of professional equipment or facility is changed, reevaluation of electromagnetic field exposure should be considered. Restricted Area of Electromagnetic Field Exposure An area with excessive electromagnetic field exposure (restricted area) is a hazardous area at a certain distance from the equipment or facility as required by exposure control limits of related regulations, so as to control public or operator exposure to electromagnetic field. Take proper measures to ensure the safe distance from electromagnetic field exposure, including but not limited to: Plan the professional equipment or facility site in an inaccessible area to the public, and do not publicize the location. Allow only authorized and instructed person to access the professional equipment or facility site. Before entering the area with excessive electromagnetic field exposure, professional personnel should know the location of the restricted area and shut down the transmitter. Set clear signs at the site to remind professional personnel that the current location is in or may be in the area with excessive electromagnetic field exposure. After site installation, conduct regular monitoring and checks. Set effective physical shields and apparent warning signs in all areas with excessive electromagnetic field exposure. Install an isolating device outside the equipment structure. Comply with local regulations in operations. Installation and Use of a Wireless Base Station Transceiver A base transceiver station (BTS) is properly designed so that its RF electromagnetic radiation is under the related standard limits of RF radiation hazard. Therefore, a normal working BTS does no harm to the public and working personnel. However, a BTS with defective antenna cables or other defects may result in excessive RF electromagnetic radiation. Professional personnel should abide by the following rules in BTS installation and operation: Before installing and operating a BTS and its antenna, read safety recommendations and comply with local regulations. Before installing or maintaining an antenna close to the tower or mast with a BTS and its antenna, contact related personnel to shut down the antenna transmitter. If necessary, working personnel at the site should carry radiation monitoring and alarm instrument. To ensure safety of public electromagnetic field exposure, abide by the following guiding principles in BTS antenna site installation: In rooftop installation, install antennas at a height over the height of personnel who may work or live on the rooftop. In rooftop installation, install transmit antennas far away from most visited areas, such as the rooftop access point, telephony service point, and HVAC equipment. In rooftop installation, install directional antennas peripherally and do not make them face towards buildings. Properly choose from large antennas (better signal coverage) and small antennas (less visual impact). Install antennas at a far site, although it may be mutually exclusive to local area requirements. Safety Information When constructing a common installation site, pay special attention to antennas from different manufacturers, especially high-power broadcasting (FM/TV) antennas. Antennas are generally installed in one common site locally, which may increase safety risks. Take special preventive measures at antenna sites next to hospitals or schools. Use of Other Wireless Equipment If any related equipment manual specifies the safe distance of electromagnetic field exposure, this distance requirement should be applied. No application distance is specified for the equipment with low RF transmit power that meets electromagnetic field exposure requirements. No application distance is specified for the equipment with special design that meets electromagnetic field exposure requirements in close use. Use of High-voltage Equipment or Facility Only the power frequency electromagnetic field generated by high-voltage (for example, over 100 kV) equipment or facility are harmful to human. Therefore, the electromagnetic field needs to be evaluated according to related requirements. 1.5.2 Laser Radiation This section describes laser safety precautions. Do not get close to optical fibers without eye protection or look directly into optical fiber terminals. A laser transceiver is used in optical transmission system and related test tools. Unterminated optical fibers or connectors will emit invisible laser with very high power density. Viewing the laser output will pose an eye hazard. Viewing bare optical fiber terminals or damaged optical fibers at a distance over 150 mm generally do not pose an eye hazard. Viewing optical fiber terminals with certain optical instruments, such as microscopes, magnifiers, and eye loupes, may pose an eye hazard. Abide by the following operation requirements to avoid laser radiation hazards: Only trained and authorized personnel are allowed to operate laser. Wear goggles in laser or optical fiber operation. Disconnect the light source before disconnecting optical fiber connectors. After disconnecting optical fiber connectors, use optical fiber caps to protect all the connectors. Do not look into unterminated optical fibers or connecter terminals until the light source is disconnected. Immediately install dust-proof caps onto optical fiber connectors. Ensure optical fibers and light source are disconnected before fiber cutting or splicing. Use an optical power meter to measure optical power and verify that the light source is disconnected. Avoid laser radiation before opening the front door of the optical transmission system. Do not view optical fiber terminals or connectors with microscopes, magnifiers, or eye loupes.

Hoisting operators must be trained and qualified before starting to work. Hoisting tools must be check to ensure tool completeness. Before hoisting, ensure that hoisting tools are securely fastened to fixed load-bearing objects or wall. During hoisting, ensure angles between lifting slings are not larger than 90°, as shown in Figure 1-2. Figure 1-2 Hoisting heavy objects Ladder Use Safety Before using a ladder, check whether the ladder is intact and confirm its load bearing capacity. Do not use it with overload. The recommended angle between the ladder and the ground is 75°. You can use a right angle to measure the angle, as shown in Figure 1-3. Place the wider ladder legs at the bottom or take protective measures at the bottom to avoid skid. Place the ladder on a stable surface. Safety Information Figure 1-3 Ladder tilt angle Pay attention to the following points when climbing a ladder: − Prevent your center of gravity from deviating from the ladder edge. − Keep your body stable before climbing to ensure safety. − Do not climb over the fourth beam from the ladder top. To climb up to a rooftop, the vertical height of the ladder above the rooftop must be more than 1 m, as shown in Figure 1-4. Figure 1-4 1 m vertical height of the ladder above the rooftop Drilling Safety Pay attention to the following safety precautions when drilling holes on the wall or ground. Do not drill holes on cabinets. Incorrectly drilled holes will damage cabinet electromagnetic shielding performance and internal cables. Metal scraps generated in drilling will cause short circuit on circuit boards in a cabinet. Wear goggles and protective gloves in drilling. Cover equipment before drilling to prevent metal scraps from entering equipment interior. Timely clear and eliminate metal scraps after drilling. Safety Information Heavy Object Transport Safety Prepare for load bearing in heavy object transport to avoid injury or sprain. When transporting a cabinet, keep your back straight and move steadily to avoid sprain. When transporting equipment with hands, wear protective gloves to avoid cut by edges. When moving or lifting a shelf, hold shelf handles or bottom edge, instead of handles of installed models in the cabinet, such as power modules, fan modules and boards. 1.7 Maintenance Safety Before replacing accessories or parts, wear an ESD wrist strap, and ensure the other end of the ESD wrist strap is grounded and the other end is properly contacted with skin. When replacing parts, take care of parts, bolts, and tools to prevent them from dropping into fans can damaging fans or equipment. When replacing shelves or parts in the cabinet, carefully pull the shelves or parts out from the cabinet to prevent unstable or heavy devices on the cabinet from causing injury or strain. Replaceable Fuse Use fuses of the same type and same rating to replace old ones. Before replacing the fuse on the panel, disconnect the equipment power supply. Otherwise, an energy hazard or electric shock may occur, causing body injury. Replaceable fuses are installed on the panel next to the AC/DC power input port or output port. Reference the specifications of backup fuses or fuses on the panel to select the fuse type for replacement. Using different fuses of different specifications may cause equipment damage, body injury, and financial loss. If the fuse rated value is silkscreened on the board, Huawei authorized personnel replace fuses according the silkscreened specifications. If the fuse rated value is not silkscreened on the board, do not maintain board fuses at site. Return them for depot repair. To replace fuses, Huawei authorized personnel replace the fuses according to the supplier model and rated value in the bill of materials (BOM). Fuse Welding Power Distribution Box and Board Replacement Before replacing a power distribution box, wear insulation gloves and ensure the external-equipment breaker is disconnected. When replacing a board, do not touch components on the board to avoid damage. Install filler panels in all vacant slots.
