Coaxial cable
The following 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.
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.

In addition, connecting FGs of the power supply module of the base unit where
the local module is mounted strengthens measures against noise.
(c) Connecting/disconnecting a coaxial cable
Be sure to shut off all phases of the external power supply used by the system.
(2) Connection of cable
(a) Connection method
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.)
