Be careful when connecting a cable so that contact failure does not occur at a
connector connection due to tension.
Identification Tag Attachment
Identification tag attachment involves attaching a marker cable tie, nameplate, and
label, and so on 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, and so
on 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 them.
When connecting the cables, always connect the ground cable first. If worker
contacts the equipment, connect a cable or perform maintenance without
connecting the ground cable, the system can be damaged or a 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 port should be capped.
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.
Make sure the work is done by personnel properly trained for the cabling job.
