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 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.
