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.

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.
Confidential
Chapter 3 Connecting Cables
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 weather proof tape at the 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 the cable so that contact failure does not occur at
the connector connection due to tension.
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.
Confidential
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, ensure not to overlap or tangle the cables. In addition, consider
future expansion. Install the DC power cable and the data transmission cable away
from the AC power cable to prevent electromagnetic induction.
Ensure that the work is done by personnel properly trained for the cabling job.
