Connection and wiring length between the converter unit and the inverter
• Perform wiring so that the commands sent from the converter unit are transmitted to the inverter without fail. Otherwise,
the converter unit and the inverter may be damaged.
• For the wiring length, refer to the following tables.
Location
Between the terminals P and P and
the terminals N and N
Other control signal cables
• For the wire gauge of the wire across the main circuit terminals P/+ and N/- (P and P, N and N), refer to
MCCB
MC
Power
supply
*1
Do not install an MCCB across terminals P/+ and N/- (between terminals P and P/+ or between terminals N and N/-). Connecting the opposite
polarity of terminals N/- and P/+ will damage the inverter.
*2
For the X10 signal input, set "10" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the function.
*3
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.)
*4
For the X11 signal input, set "11" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the function.
For RS-485 or any other communication where the start command is only transmitted once, use the X11 signal to save the operation mode at the
time of an instantaneous power failure.
*5
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
(sink logic) of the inverter. Otherwise, the converter unit may be damaged.
