These terminals are used to detect the phase and voltage of the power supply, and to input
power to the control circuit. Connect each of them to terminals of the same name on both
the power supply and the reactor. Operating the inverter without connecting them will
damage the converter.
Connect each of them to terminals of the same name on the reactor.
These terminals are connected to the phase detection terminals R/L1 and S/L2 in the initial
status. To retain the fault display and fault output, remove the jumpers (cables) and apply
external power through these terminals.
Connect them to the inverter terminals P/+ and N/-.
Connect them to the inverter terminals P/+ and N/-.
For earthing (grounding) the converter chassis. This must be earthed (grounded).
