Ver. SAFETY CONCERNS VI © SAMSUNG Electronics Co., Ltd. 2600-00F1W8GAA 4.0 Warning Power and Grounding Cautions When Using Insulation Tester Pay attention to the followings to prevent any personal injury caused by an electric shock when using an insulation tester. - Make sure the polarity is correct when connecting the Earth COM (black) and AC.V (red) lead lines. And do not touch the connected probes (inspecting part of the lead line) with a hand and avoid body contact. - Avoid body contact to the system when measuring an insulation resistance. Watches, rings, and other metallic accessories Do not wear accessories such as watches and rings in order to prevent electrical shock. Power Switch Off Make sure the power switch of power supplier is off when installing the system. Installing the system with power switch on may cause system damage or fatal human injury when cables are not correctly connected. Connecting Ground Cable When connecting the cables, always connect the ground cable first. If worker contacts the equipment, connect a cable or perform maintenance without connecting the ground cable, the system can be damaged or a worker may be injured due to static electricity and short circuit. Turning Off the Circuit Breaker before Connecting the Power Cable Since power is applied to the system where the power cable is connected by manipulating the circuit breaker of the rectifier, be sure to check the rectifier’s breaker is turned off (open) before connecting the power cable to the power connector. If the system is installed while the circuit breaker is on, the worker may be critically injured as soon as the cable is connected in the wrong way. WARNING

VII 2600-00F1W8GAA 4.0 Installation Warning for Laser Beam Running through Optical Cables In the system, the laser beam emitting light runs through the optical cable. The exposure of the laser beam on worker’s eye may cause serious injury so that it should be handled with care. Warning for Worker’s Injury When installing cables in a small area, do not apply excessive force. Worker may bump against a wall or equipment. Protection gloves and goggles Make sure that worker wears protection gloves and goggles to prevent damages from debris while drilling holes in a wall or ceiling.
Ver. SAFETY CONCERNS VIII © SAMSUNG Electronics Co., Ltd. 2600-00F1W8GAA 4.0 Caution Power and Feeder line Cautions while Cleaning Power Supply While cleaning the power supply device, take caution that the device does not come in contact with alien bodies that may cause power failure. Precautions While Measuring Insulation Resistance Observe the followings to prevent any system damage when measuring insulation resistance because there is a very high voltage. - Before measuring insulation resistance, disconnect all the cables connected to the system. - Do not measure insulation resistance when power is on. - Do not measure insulation resistance at any other positions such as system internal units or parts other than the targeted insulation resistance measuring points. System Grounding Method Ground bar for lightning protector/power/communication must be isolated from each other. These three ground bars can be grounded as the isolation grounding method, or branched from ground mesh buried in the underground as common grounding method. Precautions When Connecting Power Cable To secure rainproof performance of a cable gland, min. 11.81 in. (300 mm) straight section must be maintained. Here, the radius of curvature must be considered according to the cable specification. When Using Power Cables - When handling the power cable, ensure the power switch of a rectifier is turned off to prevent the risk from the power cable and electric short-circuit of related cables. - Because a power accident may occur when fixing parts get loosened, make sure that fasteners to fix the power cable should be firmly fastened. CAUTION
Ver. Mobile WiMAX/TD-LTE Smart MBS, U-RAS Flexible V2 RRH-B4 Installation Manual © SAMSUNG Electronics Co., Ltd. IX 2600-00F1W8GAA 4.0 Check When Fixing the Power Cable Fix the power cable and the power cable bracket using a stainless steel tie for preventing loose contact due to cable tension and leakage problems. It is recommended to use the designated tools to tighten the stainless steel tie. Caution for Rain-proof Gasket Damage Be careful the rain-proof gasket is not damaged during work, and check again the gasket is not damaged before closing power/DTA window cover. If the rain-proof gasket is damaged, replace the RRH-B4. Power Window Cover Be sure to check the circuit breaker for RRH-B4 is turned off before opening or closing the power window cover. If the cover is open or close while the circuit breaker is on, the system can be damaged or a worker may be critically injured due to electrical short-circuit. Precautions When Cutting Power Cable Install the power cable to the power port of system by considering the radius of curvature of its cable specification and then cut the cable. If you install the cable after cutting, there may be length difference among the core wires at the end of the cable because of cable curvature. This may result in poor contact after the cable is connected to the power port. Installing the Antenna When you install the antenna, the antenna must be within the protective angle (left/right side 45° each from the central axis) to prevent the antenna from lightning damage. Checking VSWR for Minimum Cable Bend Radius and Length of RF Cable If the VSWR value for minimum cable bend radius and length of RF cable is not applied, system may not work properly because RF signals cannot transmit or receive smoothly. So, the VSWR value for minimum cable bend radius and length of RF cable must be checked and applied.
Ver. SAFETY CONCERNS X © SAMSUNG Electronics Co., Ltd. 2600-00F1W8GAA 4.0 Cautions When Measuring VSWR When measuring VSWR, if you open the antenna port when the transmission output is not completely off, a spike signal may flow into the reception path, which may cause damage to LNA. Make sure the transmission output is completely off when measuring VSWR. Cable Work Sequence When performing cable work for the system, proceed with the ground work before any other work to prevent errors occurring due to static electricity and other reasons. Radius of Curvature of Feeder Line When installing a feeder line, the radius of curvature of the sections where cables bent should be larger than the allowed radius of curvature. If the radius of curvature for the feeder line installation is less than the allowed radius of curvature, it may affect the performance of the system. Connection of Feeder Cable Connector Connecting the feeder cable connector is critical process, so the qualified workers who finished the related education should perform. Installation Cautions while Cleaning the Rack Make sure that worker does not damage installed cables while cleaning the rack. Do not Work by Yourself Worker must not work alone in any key process. Managing Unused Ports Never allow foreign substances to be inserted into unused ports by covering them with a dust cap.
Ver. Mobile WiMAX/TD-LTE Smart MBS, U-RAS Flexible V2 RRH-B4 Installation Manual © SAMSUNG Electronics Co., Ltd. XI 2600-00F1W8GAA 4.0 Finishing the Cable Inlet To prevent foreign substances, outdoor air and moisture from entering the cable inlet (including cable gland and conduit), finish it as follows: - Unused inlet Use the hole finishing materials including dust cap and rubber packing. - Cable-installed inlet After cable installation, block any space in the inlet with tape, compressed sponge, rubber packing, and silicon. Management of Unused Ports Cover the unused ports (conduit, cable gland, etc.) with waterproof cap (sealing cap) to prevent infiltration of foreign material such as dust, moisture, or bug. Caution When Connecting the Optical Cable Check whether there is dust or foreign material on the cutting section of the connector core before connecting the optic cable, and keep this away from dust or foreign material. If the cable is soiled with foreign material, do not blow to remove them. Make sure to clean the connector in accordance with the cleaning directions in ‘ANNEX D’. Caution When Assembling Cable Gland If the parts of a cable gland in the system are not correctly installed, outdoor air and moisture may flow into the system and cause corrosion, system fault, or serious fault to the cooling system. Therefore, assemble and finish the cable gland accurately. Caution When Installing Cable in the Cable Gland Only one cable of permitted specification (thickness) should be installed in the cable gland. - The outdoor air or moisture may flow into the system if a cable that is thinner than the specification is used. - If a cable is thicker than the specification or more than two cables are installed, the cable gland may be damaged.
