When Supplying 24 V External Power To The Control Circuit - Mitsubishi Electric FR-A800 Series Instruction Manual

NOTE
• When using separate power supplies, always remove the 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.
• The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 differs according to the inverter
capacity.
• 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
not be held.
• When a power supply is provided for the control circuit separately from the main circuit and a capacitive device (such as an
EMC filter or a radio noise filter) is connected, refer to the following diagram. (For the wiring example to comply with ship
classification standards, refer to
2.6.6 When supplying 24 V external power to the control
circuit
Connect the 24 V external power supply across terminals +24 and SD to turn the I/O terminal ON/OFF operation, keep the
operation panel ON, and carry out communication during communication operation even at power-OFF state of inverter's main
circuit power supply. 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.
