6.9 Make any additional local user-selected

connections to the RSA III P41 connector. User-

defined inputs can be used for any status,

warning, or shutdown including open circuit

breaker, air damper, etc. The user-selection

connections are defined in Figure 43 and

Figure 44 and include:

D User Input 1 (local).

D User Input 2 (local).

D User Input 3 (local).

D User Input 4 (local).

D User Input 5 (local).

D ATS emergency input (local). Connect wiring

from the user-supplied transfer s witch (ATS)

emergency position auxiliary contacts. See the

respective ATS wiring diagram(s).

Note: User-defined digital inputs #1 to #5 are

selected at the RSA III master only and

annunciated to the RSA III slave(s). No

user-defined digital input selection is

available at the RSA III slave(s).
