contact connections. Refer to the schematic drawing
provided with the unit to identify the auxiliary contact
terminals for your model transfer switch.
Note: The contacts are shown with the transfer switch in
the Normal (Source N) position in all figures and
schematic drawings. (Contacts shown closed in
the figures are closed on Normal. Contacts
