CAUTION
 Do not use the empty terminals (NC) of the control circuit. Doing so may lead to damage of the converter unit
and the inverter.
 Always connect terminal RDA of the converter unit and terminal MRS (X10) of the inverter, and terminal SE of
the converter unit and terminal SD (terminal PC in the source logic) of the inverter. Not doing so may lead to
damage of the converter unit.
2.6.3

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 connector to the connector pin of the desired control logic.
The control logic of input signals is initially set to the sink logic (SINK).
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
NOTE
• Make sure that the jumper connector is installed correctly.
• Never change the control logic while power is ON.
Terminal function description
1 changeover contact output that indicates that the protective function of
the converter unit has been activated and the outputs are stopped.
Fault: discontinuity across B and C (continuity across A and C), Normal:
continuity across Band C (discontinuity across A and C)
Switched to LOW when the converter unit operation is ready.
Assign the signal to the terminal MRS (X10) of the inverter.
The inverter can be started when the RDA status is LOW.
Switched to LOW when a converter unit fault occurs or the converter is
reset.
The inverter can be started when the RDB status is HIGH.
Switched to LOW when the converter is reset (RES-ON).
Assign the signal to the terminal RES of the inverter.
The inverter is reset when it is connected with the RSO status LOW.
Switched to LOW when an instantaneous power failure is detected.
Switched to LOW when a cooling fan fault occurs.
Common terminal for terminals RDA, RDB, RSO, IPF, FAN
Connect this terminal to the terminal SD (sink logic) or PC (source logic)
of the inverter.

(conducted).
HIGH is when the
transistor is OFF (not
conducted).
