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 can be damaged by external factors, ensure that measures are

taken to prevent damages 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 installa tion 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.  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.

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 1.97 in. (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 i s a potential danger of contact failure in a connector connection due to tension,

install the cable in the short est dis tance.

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 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

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. Install the DC power cable and data transmission cable away from the AC power cable to prevent electromagnetic induction.
