Using Intelligent Input Terminals Section 4-5
The two diagrams below input wiring circuits using the inverter's internal
+24 V supply. Each diagram shows the connection for simple switches, or for
a field device with transistor outputs. Note that in the lower diagram, it is nec-
essary to connect terminal [L] only when using the field device with transis-
tors. Be sure to use the correct connection of the short bar shown for each
wiring diagram.
