Mitsubishi Electric FR-A802-P Instruction Manual page 52

NOTE
• When using separate power supplies, always remove the jumpers from terminals R1/L11 and S1/L21. The inverter may be
damaged if the jumpers are not removed.
• The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than
the input side of the MC.
• The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 is 80 VA.
• If the main circuit power is switched OFF (for 0.1 s 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, connect a noise filter (example: RTMN5006 manufactured by TDK-Lambda
Corporation) to the control circuit power supply.
2.6.7
When supplying 24 V external power to the
control circuit
Connect a 24 V external power supply across terminals +24 and SD. Connecting a 24 V external power supply enables
I/O terminal ON/OFF operation, operation panel displays, control functions, and communication during communication
operation even during power-OFF of inverter's main circuit power supply. When the main circuit power supply is turned
ON, the power supply changes from the 24 V external power supply to the main circuit power supply.
