Hitachi hitachi series inverter Sinking Inputs, External Supply, Sourcing Inputs, External Supply

The two diagrams below show input wiring circuits using an external supply. If using the “Sinking Inputs, External Supply” in below wiring diagram, be sure to remove the jumper wire, and use a diode (*) with the external supply. This will prevent a power supply contention in case the jumper wire is accidentally placed in the incorrect position. For the “Sourcing Inputs, External Supply”, please connect the jumper wire as drawn in the diagram below.
