The two diagrams below show input wiring circuits using an external supply. If using the
upper wiring diagram, be sure to use a diode with the external supply. This will prevent a
power supply contention in case the SR/SK switch is accidentally placed in the incorrect
position. Be sure to use the correct SR/SK switch position shown for each wiring
diagram.
