Confidential Chapter 3 Connecting Cables 5G AU Installation Manual v2.0 48 Copyright © 2017, All Rights Reserved. Guidelines for Cable Connections Figure below depicts the sequence of operations for connecting cables to the system. Figure 38. Cable Connection Procedure When cutting the cable after installation, ensure that the connector is disconnected. The cable installation while the connector is connected to the system may cause contact failure, or damage to the assembled connector and the cable, due to cable tension or operator mistakes. 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". Cable Path Inspection When installing a cable that interconnects rectifier, Main Ground Bar (MGB), and backhaul device, within the system, cable path, length, and cable installation method must be inspected. To inspect the cable path, ensure the following.  A minimum cable length must be selected, so that the length does not affect the cable installation and maintenance. Cable Installation Connector Attachment Identification Tag Attachment Connector Assembly When assembling the connector at the site Cable Path Inspection Cable Cutting Cable Binding
Confidential Chapter 3 Connecting Cables 5G AU Installation Manual v2.0 49 Copyright © 2017, All Rights Reserved.  The cable must be placed in a location where the cable is not damaged by external factors such as power line, flooding, and footpaths.  In areas where the cable may be damaged by external factors, ensure that measures are taken to prevent damage to the cable, such as cable tray, ducts, and flexible pipe. Cable Cutting Measure the exact distance after carefully checking the route, and cut the cable using a cutting tool. To cut the cable, follow these guidelines:  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 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 This process involves running the cable along the cabling path to the target connector of the system or an auxiliary device. This is done after cable path inspection and cable cutting are completed. To install the cable, follow these guidelines:  Be careful not to damage the cable.  If the cable is damaged, cut out the damaged section before installing, or replace the cable.  Run the cable so that it is not tangled. In particular, when installing the 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 ensure that the minimum curvature radius specification is complied with.  If the cable needs to be protected, use suitable protective cover such as PVC channel, spiral sleeve, flexible pipe, and cable rack.  Install the DC power cable and the data transmission cable away from the AC power cable to prevent electromagnetic induction. Table below provides the recommended minimum allowed cable bend radius of different types of cables
Confidential Chapter 3 Connecting Cables 5G AU Installation Manual v2.0 50 Copyright © 2017, All Rights Reserved. Table 16. Recommended Minimum Allowed Cable Bend Radius No Type Allowed Cable Bend Radius 1 Ground/Power Cable Eight times of the cable external diameter 2 Optical Cable (indoor) Unloaded Condition (Installed) : 20 times of cable external diameter Loaded Condition (During Installation) : 40 times of cable external diameter 3 Optical Cable (Outdoor) Unloaded Condition (Installed) : 10 times of cable external diameter Loaded Condition (During Installation) : 20 times of cable external diameter 4 UTP/FTP/S-FTP/F-UDP Cable Four times of the cable external diameter ※ If the allowed cable bend radius is specified by the manufacturer, comply with the bend radius specified. Cable Binding This process involves fixing and arranging an installed cable using binding thread, cable ties, binding wire, and ram clamps. Follow these guidelines when binding a cable.  Be careful not to damage the cable during binding.  Use proper cable binding tools according to the target location (indoor or outdoor) and the type of the cable (power supply cable, optical cable, or feeder line).  Ensure the cutting sections of the cable tie and the binding line are not exposed to the outside. This may cause damage to the cables or personal injury.  Cut off the remainder of the cable thread by leaving about 50 mm of extra length to prevent the knot from easily getting untied.  If there is a chance of contact-failure to occur in the connector connection due to tension, bind the cable at the closest location to the connector. Connector Attachment This process involves assembling a connector to an installed cable or to a device on the site. Follow these guidelines when attaching the connector.  Ensure operator is fully aware of the connector assembly method before assembling the 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 the connector to another connector.  Use a heat shrink tube at the connector connection for cables that are installed

Identification Tag Attachment This process involves attaching a marker cable tie, a nameplate, and a label to both ends of a cable (connections to a connector) to identify the use of the cable and the cabling path. Follow these guidelines when attaching an identification tag.  When installing the cable outdoor, use relief engraving and coated labels 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 the tags. When connecting the cables, always connect the ground cable first. If a worker contacts the equipment, connects a cable, or performs maintenance without connecting the ground cable, the system can be damaged or the worker may be injured due to static electricity and short circuit. 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. After completing cable installation, unused ports must be capped. When installing, take care not to overlap or tangle the cables. In addition, consider future expansion. Install DC power cable and data transmission cable away from AC power cable to prevent electromagnetic induction. Ensure the work is done by personnel properly trained for the cabling job.

Grounding Grounding is the process of operating an electronic system such as power supply system, communication system, and control system, stably without damage from lightning, transient-current, transient-voltage, and electric noise. Grounding also helps in preventing injury from electric shock. Ground equipment minimizes the electrical potential of the electronic device to that of the ground, which is zero electrical potential. This prevents electrification of the electronic device. Connect the ground cable first. In cabling, the connection of cables without the connection to the ground cable may cause damage of the equipment or bodily injury to personnel. The purposes of the ground construction are as follows:  To prevent human life and the system from over-current, over-voltage, and lightning  To provide a discharge path for surge voltage generated by lightning and power switch  To protect the system from static electricity  To eliminate or minimize the high-frequency potential in the system housing  To provide a conductor for the balance and stability of high-frequency current  To stabilize the potential of the circuit against the ground Connecting Ground Cable To connect a ground cable 1 Ensure that the items mentioned in below table are available.

Power Equipment Elements 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 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 get critically injured if the cable is connected in the wrong way. Handling the power cable incorrectly may damage the rack or cause an electric short-circuit through the cable. Ensure the power switch of the rectifier or the system is turned off before handling the power. The fasteners for power cable must be tightly secured to prevent electrical accidents. The heat-resistant temperature of the power cable should be 90°C or more. Install the power cable to the power port of the system by considering the radius of curvature of its cable specification and then cut the cable. If operator installs 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. If you turn the power on and off rapidly (within 1 s), the counter electromotive force caused by cable inductance can damage the system. Connecting more than one power cable together may increase power loss. It must be verified that the rectifier or the power distributor has an output voltage within the specified system input range before the power line is connected. 100~240 VAC AU [AC Type] AC Distributor -48 VDC AU DC Distributor [DC Type] 메모 포함[SSK1]: This element is not shown in the figure.
