    INTRODUCTIONThis instruction manual provides information about the operation and installation of the BE1-951Overcurrent Protection System. To accomplish this, the following information is provided:

    General information, specifications, and a Quick Startguide.

    Functional description and setting parameters for the inputs and outputs, protection and controlfunctions, metering functions, and reporting and alarm functions.

    BESTlogic programmable logic design and programming. Documentation of the preprogrammed logic schemes and application tips.

    Description of security and user interface setup including ASCII communication and the human-machine interface (HMI).

    Installation procedures, dimension drawings, and connection diagrams.

    Description of the front panel HMI and the ASCII command interface with write access securityprocedures.

    A summary of setting, metering, reporting, control, and miscellaneous commands.

    Testing and maintenance procedures.

    Description of BESTCOMS graphical user interface (GUI).

    Appendices containing time overcurrent characteristic curves and an ASCII command-HMI crossreference.

    Optional instruction manuals for the BE1-951 include:

    Distributed Network Protocol (DNP) 3.0 (9328900992)



    To avoid personal injury or equipment damage, only qualified personnel shouldperform the procedures in this manual.


    Be sure that the relay is hard-wired to earth ground with no smaller than 12 AWGcopper wire attached to the ground terminal on the rear of the unit case. Whenthe relay is configured in a system with other devices, it is recommended to use aseparate lead to the ground bus from each unit.
