1.1 Introduction
The Remote Control unit is used to connect the Fusesaver pole mounted circuit breaker or CMR
Compact Modular Recloser into a utility SCADA system. The Remote Control Unit is a pole mounted
enclosure containing a microprocessor, a short range (approximately 20 m) radio used to
communicate with the switchgear and a long range radio (or modem). The long range radio (or
modem) is not supplied or fitted by Siemens unless specifically agreed to in the sale contract.
Successful application and operation of this equipment depends as much upon proper installation
and maintenance by the user as it does upon the proper design and fabrication by Siemens.
1.2 Format and aim of the operating instructions
These operating instructions apply for the Remote Control Unit.
The purpose of this instruction manual is to assist the user in developing safe and efficient
procedures for the installation, maintenance and use of the equipment.
These instructions are intended to familiarise personnel with the mechanical and electrical design
as well as the general functionality of the Remote Control Unit. These instructions also include notes
on operation and information concerning installation and maintenance.
It is required that operating and installation personnel familiarise themselves early as possible with
the instructions and other documents provided, in order to gather any relevant further information on
the Remote Control Unit and its features.
In written or verbal communications, please provide the complete description from the operating

used in these locations.
Contact the nearest Siemens representative if any additional information is desired.
