Rockwell Automation 140U N-Frame CB Alarm Switch and Alarm Auxiliary Switch Combination - Manual (Page 2)

Where local codes and standards permit and UL listing
is not required, internal accessories can be field
installed in sealed circuit breakers. In this case, UL list
i
ng becomes invalid and the label should be removed.
File E7819.
Before attempting to install the ASL switch or acces-
sory combination, check that the catalog number is
correct as ordered and that the rating of the acces-
sory(s) satisfies the job requirements.
Depending on the model ordered, connections for the
ASL switch and auxiliary switch contacts are in one of
four forms. The standard wiring configuration is pigtail
leads exiting the rear of the base directly behind the
accessory. Optional configurations include a terminal
block mounted on the same side of the base as the
accessory, leads exiting the side of the base where the
accessory is mounted, and leads exiting the rear of the
base on the side opposite the accessory. The 18-inch
long pigtail leads are color coded for identification; iden-
tification labels are provided for pigtail leads and termi-
nal block points. For allowable locations of all acces-
sories, refer to
Selection Guide.
No more than three pigtail leads can be routed
through the rear trough in the circuit breaker base.
This instruction leaflet (IL) gives detailed procedures for
installing the ASL switch and ASL switch/auxiliary switch
combination (accessory combination).
