CAUTION
Do not use the empty terminals (NCs) of the control circuit. Doing so may lead to damage of the converter unit
and the inverter.
Always connect between terminal RDA of the converter unit and terminal MRS (X10) of the inverter, and between
terminal SE of the converter unit and terminal SD (terminal PC in the source logic) of the inverter. Failure to do
so may lead to damage of the converter unit.
2.6.3
Control logic (sink/source) change
Switch 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.

INSTALLATION AND WIRING
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)
The output is in LOW state when the converter unit operation is ready.
Assign the signal to terminal MRS (X10) of the inverter.
The inverter can be started when the RDA status is LOW.
The output is in LOW state when a converter unit fault occurs or the
converter is reset.
The inverter can be started when the RDB status is HIGH.
The output is in LOW state when the converter is reset (RES-ON).
Assign the signal to terminal RES of the inverter.
The inverter is reset when it is connected with the RSO status LOW.
The output is in LOW state when an instantaneous power failure is
detected.
The output is in LOW state when a cooling fan fault occurs.
Common terminal for terminals RDA, RDB, RSO, IPF, FAN
Connect this terminal to terminal SD (sink logic) or PC (source logic) of
the inverter.
