The D77B-DSNAP will auto configure to the S751 Starter when the D77B-DSNAP and the
IT.
Starter are first powered (together). After the auto configuration is complete, the D77B-DSNAP
is “married” to that specific size, and overload range of S751. Any attempt to install an already
“married” D77B-DSNAP onto another S751 without first performing a reset (Appendix, Page
30) will result in the D77B-DSNAP entering a recoverable fault state (flashing red MS/NS LED);
the D77B-DSNAP will not operate the
IT. Starter.
