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.
Terminal name
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)
Switched to LOW 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.
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 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 the contact input terminal (sink logic) and
terminal FM.
Connect this terminal to the power supply common terminal of a
transistor output (open collector output) device, such as a
programmable controller, in the source logic to avoid malfunction by
undesirable current.
Common terminal for the 24 VDC power supply (terminal PC,
terminal +24).
Isolated from terminals 5 and SE.
Connect this terminal to the power supply common terminal of a
transistor output (open collector output) device, such as a
programmable controller, in the sink logic to avoid malfunction by
undesirable current.
Common terminal for contact input terminal (source logic).
Common terminal for terminals RDA, RDB, RSO, IPF, FAN
Connect this terminal to terminal SD (sink logic) or PC (source logic)
of the inverter.
