The two diagrams below input wiring circuits using the inverter’s internal +24V 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 necessary to connect terminal
[L] only when using the field device with transistors. Be sure to use the correct
connection of the short bar shown for each wiring diagram.
