Control Logic (Sink/Source) Change; When Supplying 24 V External Power To The Control Circuit - Mitsubishi Electric FR-A800 Installation Manuallines

3.4.4 Control logic (sink/source) change

Change the control logic of input signals as necessary.
To change the control logic, change the jumper connector position on the control circuit board. Connect the jumper con-
nector to the connector pin of the desired control logic.
The control logic of input signals is initially set to the sink logic (SINK) for the FM type.
The control logic of input signals is initially set to the source logic (SOURCE) for the CA type.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)

3.4.5 When supplying 24 V external power to the control circuit

Connect the 24 V external power supply across terminals +24 and SD. The 24 V external power supply enables I/O termi-
nal ON/OFF operation, operation panel displays, control functions, and communication during communication operation
even during power-OFF of inverter's main circuit power supply.
During the 24 V external power supply operation, "EV" flickers on the operation panel.
