[1]Auxiliary contacts are only available when option 13IC (add isolation contactor) is selected on SMC-2, SMC PLUS, and SMC Dialog Plus units. When 13IC is selected, the maximum number of auxiliary contacts is as follows:

?for 5A SMC-2 units without SCR fusing (option 13SCR): four (4) in any combination except (3) N.O. with (1) N.C. or (1) N.O. with (3) N.C.?for 5A SMC-2 units with SCR fusing (option 13SCR): four (4) in any combination.?for 9A through 16A SMC-2 units: four (4) in any combination.?for 24A through 500A SMC PLUS units: four (4) in any combination.?for 24A through 500A SMC Dialog Plus units: four (4) in any combination.When ON-OFF pilot lights are selected on SMC-2 units, select 1 N.C. auxiliary contact (option 91). When ON pilot light is selected on NEMA Type 12 SMC PLUS and SMC Dialog Plus units, select (1) N.O. auxiliary contact (option 90).When ON-OFF pilot lights are selected on NEMA Type 12 SMC PLUS and SMC Dialog Plus units, select (1) N.O. and (1) N.C. auxiliary contact (options 90 and 91). [2]Bulletin 150 SMC-3 controller includes (1) N.O. auxiliary contact set to NORMAL. Maximum number of additional auxiliary contacts for SMC-3 units without option 13IC (add isolation contactor) is (2) in the following combinations: (1) N.O., (1) N.C., (2) N.O., or (1) N.O. and (1) N.C. These auxiliary contacts areside-mounted on SMC-3 and set to NORMAL. Maximum number of additional auxiliary contacts for SMC-3 units with option 13IC (add isolation contactor) is (4), in any combination. These auxiliary contacts are on the 13IC isolation contactor.When ON-OFF pilot lights are selected on SMC-3 units, select (1) N.C. auxiliary contact (option 91). When ON-OFF pilot lights and DeviceNet Starter Auxiliary (option 13DSA_) are selected on SMC-3 units, select (1) N.O. and (1) N.C. auxiliary contact (options 90 and 91). When ON pilot light and DeviceNet Starter Auxiliary (option 13DSA_) are selected on SMC-3 unit, select (1) N.O. auxiliary contact (option 90).

[3]The following apply to auxiliary contacts for Bulletin 2154J and 2155J SMC Flex units:?When isolation contactor (Option 13IC) is selected, the maximum number of auxiliary contacts is four (4) in any combination.?When isolation contactor (Option 13IC) is not selected, the maximum number of auxiliary contacts is four (4) in the following combinations: (2) N.O. / (2) N.C.; (3) N.O. / (1) N.C.;(4) N.O.; or (4) N.C.?Select (1) N.O. auxiliary contact (Option 90) when ON pilot light is selected.?Select (1) N.O. and (1) N.C. auxilary contact (Option 90 and 91) when ON-OFF pilot light is selected.?Select (1) N.O. auxilary contact (Option 90) when DeviceNet Starter Auxilary (Option 13DSA_) is selected. [4]The maximum number of auxiliary contacts that can be supplied is two (2), in any combination. Contacts actuate with movement of unit handle to ON or OFFposition only. Contacts are not designed to actuate as a result of a circuit breaker trip. For such applications, auxiliary contacts “mounted internally” (98X or99X) must be selected. Auxiliary contacts are supplied unwired. [5]The maximum number of auxiliary contacts that can be supplied internally is (2) N.O. and (2) N.C. (form C). Internal auxiliary contacts (98X or 99X) are wiredto a 3-point floating terminal block.
