8.6 FL-net Network Installation Procedures
8.6.1 10BASE5 coaxial cable wiring
(1) Cable laying/wiring
The cable can be laid and wired by various methods depending on the installation site.
Typical methods are enumerated below:
• Wall-surface exposed cable wiring
• Free-access, floor-pit inner cable wiring
• Cable rack inner cable wiring
• Above-ceiling unfixed cable wiring
(2) Cable laying/wiring precautions
Observe the following cable laying/wiring precautions:
• Under normal conditions, the 10BASE5 coaxial cable is to be laid and wired indoors.
• When fastening the cable to a wall surface or the like, clamp it at spacing intervals of about
1 m unless special conditions are imposed. Failure to observe this precaution will cause the
cable to be stressed by its own weight. When clamping the cable in this manner, exercise
care not to deform it.
• When fastening the cable to a cable rack or ceiling, clamp it at appropriate spacing intervals to
avoid cable deformation.
• When laying the cable under the floor or near the floor surface, you should protect it because
it can be easily deformed or damaged by pedestrians or furniture.
• In the interest of safety, the cable's outer conductor should be grounded.
• When establishing a ground connection, provide Class D or higher grounding at one point of a
segment.
• To prevent exposed metal portions of the cable except a grounding point from coming into
contact with the earth ground or extraneous metal surface, insulate N-type connectors, L-type
connectors, linear sleeves, and terminators by covering them with the supplied boots or
wrapping insulating tapes around them.
• Ensure that the cable is positioned at least 60 cm away from a power cable (100 VAC or
higher voltage).
