IV 310 RRH-2WB (TD-LTE Fx) Installation Manual Warning WARNING Power and Grounding 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. Warning for Connecting the Ground Cable In cabling, the connection of cables without the connection to the ground cable may cause the damage of the equipment or the injury of the worker. Connect the ground cable first. 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. 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. © SAMSUNG Electronics Co., Ltd. 310 RRH-2WB (TD-LTE Fx) Installation Manual Caution 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. Handling the Power Cable - Handling the power cable incorrectly may damage the rack or cause an electric shock through the cable. Ensure the power switch on the rectifier or the system is turned off before handling the power cable. - The fixing materials for power cable must be tightly secured to prevent electrical accidents. Power cable In case of using AWG8 (6 mm × 2C) power cable, it is applicable up to 70 m (299.66 ft). When the distance is 70 m (299.66 ft), followings should be considered. - Do not rapid ON/OFF (within one second): The voltage loss value caused by the cable resistance loss is 3 V, and the RRH-2WB could be damaged by the counter electromotive force caused by the cable inductance. - The battery’s life could be shorten: The RRH-2WB could be off in spite the battery remains. (When the battery capacity is designed within one hour) - Do not use the power cables linked: Using the power cables linked each other, the loss will be increased. Precautions for Measuring Insulation Resistance Since a high voltage is used for measuring insulation resistance, insulation resistance should not be measured when the system is in operation. Make sure to only measure the insulation resistance of the appointed part. Other components such as the system’s internal components and the unit (system frame), components of the communication cables, units, etc. should not be measured. 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. © SAMSUNG Electronics Co., Ltd. VI 310 RRH-2WB (TD-LTE Fx) Installation Manual Connection of Feeder Cable Connector Connecting the feeder cable connector is critical process, so the qualified workers who finished the related education should perform. 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. Installation Cautions while Cleaning the Rack Make sure that worker does not damage installed cables while cleaning the rack. System Installation and Access Only authorized workers are allowed to install or access the system. Do not Work by Yourself Worker must not work alone in any key process. 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 When connecting the optical cable, be careful to keep the cutting section of the connector core away from dust and foreign substances. If the cable is soiled with foreign substances, do not blow on the cable to remove them. Make sure to remove the dust or foreign substances in accordance with the cleaning instructions provided by the connector manufacturer. © SAMSUNG Electronics Co., Ltd. VII 310 RRH-2WB (TD-LTE Fx) Installation Manual Finishing Heat Shrink Tube of a Sector Antenna 1) Insert an antenna protection plate to antenna port. 2) Place the heat shrink tube on the connection point and shrink the heat shrink tube using a heat gun. Avoid aiming the heating gun toward the antenna’s body. Installing the Antenna When you install the antenna, the distant and angle between the antenna and lightning rod must be within the protective angle (left/right side 45° each from the central axis) to prevent the antenna from lightning damage.

Leveling can be carried out using a vinyl hose, a balance weight, or a level. However, levels are used for this system. Leveling Using a Level 1) 2) 3) Attach a level to the top, left, and right of the system. Adjust the system height so that the bubble in the level moves to the center of the window. (In the case of a digital level, the LCD should indicate an even plane.) Leveling is complete when the bubble stays at the window center in every level. Leveling Test for Wall Type System (Before Fixing the Anchor Bolt) 1) Before fixing the anchor bolts, draw a vertical and a horizontal between the markings of the anchor bolts, as shown in the Figure below. Make the lines vertical/horizontal using a spirit level. 2) When the lines are not placed in vertical/horizontal, complying with the distance to fix the equipment, modify the markings of the anchor bolts until the lines are placed in vertical/horizontal. Measuring for horizontal section Horizontal line 90° Vertical line Measuring for vertical section 90° Figure 2.30 Leveling Test before Fixing Anchor Bolts © SAMSUNG Electronics Co., Ltd. 2-31 310 RRH-2WB (TD-LTE Fx) Installation Manual 3) After fixing the equipment, place a spirit level on the side and top of the equipment, test the vertical/ horizontal leveling. 4) If the leveling result shows that the equipment is not placed in vertical/horizontal, check and adjust the drilling location, connection materials’ dimensions, and structures’ dimensions and then make the equipment place in vertical/horizontal. Measuring Horizontal Position Measuring Vertical Position Figure 2.31 Leveling Test before Fixing System © SAMSUNG Electronics Co., Ltd. 2-32 310 RRH-2WB (TD-LTE Fx) Installation Manual 2.6 Insulation Test When conducting an insulation test, it is advised to set the insulation tester to DC 500 V and the insulation value is recommend as 100 MΩ or higher. 1) 2) 3) Connect a lead of an insulation tester to the Hex.bolt for fixing the RRH-2WB. Connect another lead to the anchor bolt. Measure the insulation resistance by using the insulation tester. The insulation resistance should be over 100 MΩ. If the measured resistance is less than 100 MΩ, the value indicates the insulation failure. Thus, check the following and perform the insulation test again. Check if the connection between the Hex.bolt for fixing the RRH-2WB and the anchor bolt is proper. (Note that the anchor bolts must be shielded with an insulated bushing.) Check if the insulated bushing is damaged. Replace the insulator (insulated bushing, bakelite, rubber pad, etc.) or parts for fixing. Anchor Bolt Measuring Instrument of Insulation Resistance Hex.bolt for Fixing the RRH-2WB Figure 2.32 Schematic Diagram for Insulation Test Precautions for Measuring Insulation Resistance Since a high voltage is used for measuring insulation resistance, insulation resistance should not be measured when the system is in operation. Make sure to only measure the insulation resistance of the appointed part. Other components such as the system’s internal components and the unit (system frame), components of the communication cables, units, etc. should not be measured. © SAMSUNG Electronics Co., Ltd. 2-33 310 RRH-2WB (TD-LTE Fx) Installation Manual CHAPTER 3. Connecting Cables 3.1 Work Flow for Cabling The cabling sequence is as follows. Cable Path Inspection Cable Cutting Cable Installation Cable Binding Connector Attachment When assembling the connector at the site Connector Assembly Identification Tag Attachment Figure 3.1 Work Flow for Cabling Cabling Workflow The sequence of cable cutting and installation of the cable workflow can be changed depending on the field situation such as ‘cutting after installing’ or ‘installing after cutting’. Considerations when Cutting the Cable after Installation When cutting the cable after installation, make sure that the connector is disconnected. Installation of the cable with the connector connected to the system may cause contact failure or damage to the connector assembled to the system and the cable due to cable tension or the operator’s mistakes. © SAMSUNG Electronics Co., Ltd. 3-1 310 RRH-2WB (TD-LTE Fx) Installation Manual Cable Path Inspection When installing a cable that connects between the rectifier, Main Ground Bar (MGB), and backhaul device, etc. within the system, the cable path length and the cable installation method, etc. must be inspected. Follow these guidelines when inspecting the cabling path. A minimum cable length must be selected provided that it does not affect the cable installation and maintenance. The cable must be placed in a location where it will not be damaged by external factors. (power line, flooding, footpaths, etc.) In areas where the cable may be damaged by external factors, ensure that measures are taken to prevent damage to the cable. (cable tray, ducts, flexible pipe, etc.) Cable Cutting Measure the exact distance, carefully checking the route, and cut the cable using a cutting tool. Follow these guidelines when cutting the cable. Cut the cable to the length determined in the Cable Path Inspection step. Use a dedicated cable cutting tool. Cut the cable at right angles. Be careful to keep the cable away from any moisture, iron, lead, dust or other foreign material when cutting. Remove any foreign material attached to the cable using solvent and a brush. Cable Installation Cable installation involves running the cable along the cabling path to the target connector of the system or an auxiliary device after cable path inspection and cable cutting have been completed. Follow these guidelines when installing a cable. Be careful not to damage the cable. If the cable is damaged, cut out the damaged section before installing. When installing the cable over other cables, make sure the cable is installed on the other cables. Pay more attention to the vertical and horizontal cross sections where the cables are usually reversed. Always use the maximum curvature radius possible, and make sure that the minimum curvature radius specification is complied with. If the cable needs to be protected, use a PVC channel, spiral sleeve, flexible pipe, and cable rack, etc. © SAMSUNG Electronics Co., Ltd. 3-2 310 RRH-2WB (TD-LTE Fx) Installation Manual Table 3.1 Recommended Minimum Allowed Cable Bend Radius No Type Recommended Minimum Allowed Remark Cable Bend Radius GV/CV/FR-8 8 times of the cable external diameter 0.6/1 KV Cable Optic Cable 20 times of the cable external diameter UTP/FTP/S-FTP Cable 4 times of the cable external diameter PVC/LSZH, 4 Pair 1/2 in.

Repeated 15 mm (0.59 in.) ※ If the allowed cable bend radius is specified by the manufacturer, comply with the bend radius specified. Cable Binding Cable binding involves fixing and arranging an installed cable using binding strings, cable ties, binding lines, and ram clamps, etc. Follow these guidelines when binding a cable. Be careful not to damage the cable during binding. Use appropriate cable binding tools according to the target location (indoor or outdoor, etc.) and the use of the cable (power supply cable, optical cable, feeder line, etc.). Do not let the cutting section of a cable tie and binding line, etc. be exposed to the outside. This may cause damage to cables or personal injury. Make sure that the cutting sections of cables are not exposed to the outside. If there is a danger that contact failure may occur in a connector connection due to tension, install the cable as short as possible. Connector Attachment Connector attachment involves assembling a connector to an installed cable or to a device on the site. Follow these guidelines when attaching a connector. Make sure you are fully aware of the connector assembly method before assembling a connector. Assemble the connector in accordance with its pin map. Each connector has a hook to prevent its core positions from being changed. Check the corresponding grooves before connecting a connector to another connector. Trim the remaining string of any knot in a binding string so that the knot does not loosen. © SAMSUNG Electronics Co., Ltd. 3-3 310 RRH-2WB (TD-LTE Fx) Installation Manual Use a heat shrink tube at a connector connection for cables that are installed outdoor, such as feeder lines, to prevent water leakage and corrosion from occurring at the part exposed to the outside. Connect each cable of the connector assembly in a straight line. Be careful when connecting a cable so that contact failure does not occur at a connector connection due to tension. Identification Tag Attachment Identification tag attachment involves attaching a marker cable tie, nameplate, and label, etc. to the both ends of a cable (connections to a connector) to identify its use and cabling path. Marker Cable Tie On the marker cable tie, a label can be attached. The appearance and specification may differ depending on the type and manufacturer. Follow these guidelines when attaching an identification tag. When installing a cable outdoor, use relief engraving and coated labels, etc. to prevent the markings from being erased. Since the form and attachment method for identification tags are different for each provider, consult with the provider before attaching them. Connecting Ground Cable In cabling, the connection of cables without the connection to the ground cable may cause the damage of the equipment or the bodily injury of the worker. Connect the ground cable first. 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. Cable Installation Checklist When installing, take care not to overlap or tangle the cables; also, consider future expansion. Install the DC power cable and data transmission cable away from the AC power cable to prevent electromagnetic induction. Cable Works The cable works require the knowledge for the cabling works such as cable installation/tying. © SAMSUNG Electronics Co., Ltd. 3-4 310 RRH-2WB (TD-LTE Fx) Installation Manual 3.2 Cabling The cabling diagram of the RRH-2WB is as follows: [MGB] Optic Cable (for DU) [DU] RRH-2WB Frame Ground Cable 2) Power Cable 3) 1) [RF Antenna] 4) RF Antenna Cable Ground Kit [TGB] TGB Ground Cable [Rectifier] ※ TGB and Ground Kit are used when using the 7/8 in. feeder line or more.

Sector Antenna Installation A.1 Cautions when Installing a Sector Antenna Precautions of antenna installation are as follows. Sector antennas should be installed vertically. (± 1°) Antenna is the precise material, so be careful not to make damage or form change. When moving antenna, use the tool suitable to rating. In addition, use the rated carrying device which is at least 200 % or more than antenna considering the stability. Be careful not to give too much strength to the antenna. If it rains, suspend connecting the feeder cable and antenna. Fix it after adjusting the direction of antenna exactly. Distance between steel tower and antenna and the distance between send-receive antennas are based on the antenna layout. Attach the antenna on the position specified in the drawing. Install the antenna not to make a feature change of the antenna considering the direction of the radiation Connect the antenna not making the alien substance flowed so that Passive InterModulation Distortion (PMID) is not affected. Measure VSWR of all antennas and the value should be within the regulated value. A.2 Sector Antenna Layout The method of sector antenna layout is as follows. 1) 2) 3) 4) Use the transit to adjust the antenna installation direction exactly. Fix the direction of the sector antenna, same as the angle settled when designing the cell after installing the steel tower. Arrange the antennas of each sector to the sector directional angle at right angles by adjusting the distance between antenna and steel tower. In the event of the station whose the direction between sectors is not 120°, install it to make the steel tower and antenna direction different being careful of the tilt and azimuth. For circular platform, separate the antenna interval at maximum. © SAMSUNG Electronics Co., Ltd. A-1 310 RRH-2WB (TD-LTE Fx) Installation Manual A.3 Sector Antenna Installation The method of sector antenna installation is as follows. 1) Put up an antenna pole and insert the sector antenna into the antenna pole using a fixing clamp. 2) Set the antenna’s up/down tilt to 0° and fix the fixing clamps at the top and bottom. 3) After tightening the fixing clamp, adjust the antenna up/down (tilt) depending on the signal strength. The bolt of the guide clamp must be loosened, so the antenna angle can be adjusted. 4) After setting the antenna angle, tighten the bolt of the guide clamp, which was loosened previously. Regarding the nut, the double nut mounting should be used to prevent the nut from coming loose.
