Fusesavers. The Siemens FS is equipped with a short- range radio (range approximately 65.6 ft (20 m)) to allow configuration and control. In order to connect the FS into a utility SCADA system, a RCU is required.
RCU external features As shown in Figure 3, the RCU enclosure in mounted to the pole using the pole- mounting bracket. Various options for how the pole-mounting bracket connects to the pole and the installation methods are discussed in section RCU mounting on page 25.
Electronics housing The electronics housing contains the microprocessor, battery, power connection terminals, data connection points and the user interface for the RCU. The RCU has a simple user interface for operations and maintenance purposes. The RCU front panel is shown in Figures 5 and 6. It has a number of LED indictors.
