*1 To use separate power supply for the control circuit, remove each jumper at terminal R1/L11 and terminal S1/L21.
*2 The function of these terminals can be changed using the Input terminal function selection (Pr.178, Pr.187, Pr.189).
*3 The function of these terminals can be changed using the Output terminal function selection (Pr.195).
*4 The function of these terminals can be changed using the Output terminal function selection (Pr.190 to Pr.194).
*5 This connector is for manufacturer setting. Do not use.
*6 Plug-in options cannot be used.
*7 For manufacturer setting. Do not use.
*8 To use the RDA signal of the converter unit, select the normally-closed contact input specification for the input logic of the MRS signal or X10
signal of the inverter.
To use the RDB signal of the converter unit, select the normally-open contact input specification for the input logic of the MRS signal or X10 signal
of the inverter.
(For changing the input logic, refer to the Instruction Manual of the inverter.)
