2.6.2 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).

Relay output 1 (fault
output)
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 B and C (discontinuity across A and C) Contact capacity: 230

Open collector
RDA
*1
Inverter operation
enable (NO contact)
Switched to LOW when the converter unit operation is ready.
Connect this terminal to terminal MRS (X10) of the inverter.
The inverter can be started when the RDA status is LOW. Permissible load: 24 VDC
(27 VDC at maximum) 0.1

(The voltage drop is 2.8 V
at maximum while the
signal is ON.)
The open collector
transistor is ON
(conductive) in LOW
state.
The transistor is OFF (not
conductive) in HIGH
state.
RDB
*1
Inverter operation
enable (NC contact)
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.
RSO
*1
Inverter reset
Switched to LOW when the converter is reset (RES-ON).
Connect this terminal to terminal RES of the inverter.
The inverter is reset when it is connected with the RSO status LOW.
IPF
*1
Instantaneous power
failure
Switched to LOW when an instantaneous power failure is detected.
FAN
*1
Cooling fan fault Switched to LOW when a cooling fan fault occurs.

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 the terminal RDA of the converter unit and the terminal MRS (X10) of the inverter, and the terminal SE
of the converter unit and the terminal SD (terminal PC in the source logic) of the inverter. Not doing so may lead to
damage of the converter unit.
