5.2 Coaxial Cable
This section describes how to connect a coaxial cable with the local
module.
(1) Precautions for wiring
(a) Securing of wiring space
When a coaxial cable is connected with the local module, a
cable bend radius is restricted.
(b) Laying a coaxial cable
When laying a coaxial cable, keep a distance of 100mm (3.94
inch) or more from other power cables or control cables.
In addition, connecting FGs of the power supply module of the
base unit where the local module is mounted strengthens
measures against noise.
(c) Installing/removing a coaxial cable
Be sure to shut off all phases of the external power supply
used by the system.
(2) Connection of cable
A coaxial cable connects OUT(F-SD, R-RD) and IN (F-RD, R-SD)
as shown below. (OUT(F-SD, R-RD) of the last station is connected
to IN (F-RD, R-SD) of the master station.)
