When using separate power supplies for power terminal block for control circuit (R1/L11 and S1/L21), always remove the 1 jumpers across terminals R/L1 and R1/L11 and across S/L2 and S1/L21. The inverter may be damaged if the jumpers are not removed. When the control circuit power is supplied from other than the input line of the MC, the voltage of the separate power supply must be the same as that of the main control circuit. 2 The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 differs according to the inverter capacity.
3 4 If the main circuit power is switched OFF (for 0.1 second or more) then ON again, the inverter is reset and a fault output will 5 When a power supply is provided for the control circuit separately from the main circuit and a capacitive device (such as an not be held. EMC filter or a radio noise filter) is connected, refer to the following diagram.

When the main circuit power supply is turned ON, the power supply is switched from the 24 V external power supply to the main circuit power supply. Specification of the applied 24 V external power supply *1 Prepare a 24 V external power supply according to the rated specification.
