CNTL
* Installed inside respective unit.
Use with existing antenna cable (RW-9600) in case of retrofit. The maximum length of
the antenna cable is 100 m.
The white, red, and green wires are not used. Attach a single crimp-on lug (FV5.5-
S4(LF), yellow) locally to the wires. (These wires will be connected together with the
shield of the power line, in the next section.)
