15-6 Installation of an FL-net network
[1] Wiring 10BASE5 coaxial cable
(1) Laying and connecting cables
Various installation methods can be used, depending on local conditions. The major wiring methods
are shown below.
Exposed wiring on a wall.
Free access, wiring beneath the floor.
Wring inside cable racks
Laying cable in the ceiling.
(2) Precautions for laying and hooking up
Please observe the following precautions when laying cable and hooking up a network.
In principle, conduct all work indoors.
Cables may be stressed when secured on a wall. Except in special cases, provide support for the
cable at approximately 1 m intervals. Be careful not to deform the cables when securing them.
When laying cables inside cable racks or in the ceiling, secure them at appropriate intervals so
that the cables will not sag.
When laying cables below the floor or next to a wall, provide protective covers for the cables to
avoid damage from foot traffic or carts.
It is best to ground the external shield on the cables.
When grounding, ground only one point of each segment using class 3 grounding techniques.
In order to prevent contact between the conductor and exposed metal on any other device , apply
boots or insulation tape to "N" and "L" type connectors, linear sleeves, and terminators.
Make sure the cable is always at least 60 cm away from AC power cables (more than 100 VAC).
