(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. 1-8 Be careful not to damage the cable. If the cable is damaged, cut out the damaged section before installing. Run the cable so that it is not tangled. In particular, when installing a cable from a horizontal section to a vertical section, be careful not to reverse the upper and lower lines of the cable. 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.

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. Trim the binding string so that you have about 5 cm of string left from the knot. And insert the remaining string into the knot and make sure the knot does not loosen. If there is a potential danger of contact failure in a connector connection due to tension, install the cable in the shortest distance. © SAMSUNG Electronics Co., Ltd. 1-9 CHAPTER 1. Before Installation 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. 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 not to trigger contact failure at a connector connection due to tension. Identification Tag Attachment Identification tag attachment involves attaching a butterfly cable tie, nameplate, and label, etc. to the both ends of a cable (connections to a connector) to identify its use and cabling path. Follow these guidelines when attaching an identification tag. When installing a cable outdoor, use relief engraving and coated labels, etc. to prevent 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 Installation Checklist When installing, take care not to overlap or tangle the cables; also, consider future expansion.

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 When connect the connector to the antenna, not making the alien substance flowed and is not under the influence of PIMD. 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) Use the transit to adjust the antenna installation direction exactly. 2) Fix the direction of the sector antenna, same as the angle settled when designing the cell after installing the steel tower. 3) 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. 4) For circular platform, separate the antenna interval at maximum. © SAMSUNG Electronics Co., Ltd. A-1 ANNEX A. Sector Antenna Installation 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, fasten 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.
