
When using separate power supply for the control circuit, remove the jumpers from R1/L11 and S1/L21.

The function of these terminals can be changed with the input terminal assignment (Pr.178, Pr.187, Pr.189).

The function of these terminals can be changed with the output terminal assignment (Pr.195).

The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194).

The connector is for manufacturer setting. Do not use.

Plug-in options cannot be used.

For manufacturer setting. Do not use.

To use the RDA signal of the converter unit, select the NC contact input specification for the input logic of MRS signal or X10 signal of the
inverter.
To use the RDB signal of the converter unit, select the NO contact input specification for the input logic of MRS signal or X10 signal of the
inverter. (For changing the input logic, refer to the Instruction Manual of the inverter.)
NOTE
• To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, separate the
main circuit cables at the input side from the main circuit cables at the output side.
• After wiring, wire offcuts must not be left in the inverter or the converter unit.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter and the converter unit clean.
When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the
inverter or the converter unit.
