When connecting the high power factor converter (FR-HC2) to suppress power harmonics, perform wiring securely as follows. Incorrect connection will damage

the high power factor converter and the inverter.

After making sure that the wiring is correct and secure, set the rated motor voltage in Pr.19 Base frequency voltage (under V/F control) or Pr.83 Rated motor

voltage (under other than V/F control) and "2 or 102" in Pr.30 Regenerative function selection. (Refer to the FR-A800 Instruction Manual (Detailed).)



Remove jumpers across terminals R/L1 and R1/L11 as well as across terminals S/L2 and S1/L21, and connect the power supply for the control circuit to terminals R1/

L11 and S1/L21. Do not connect anything to power input terminals (R/L1, S/L2, and T/L3). Incorrect connection will damage the inverter. (The E.OPT fault (Option fault)

occurs. (Refer to the FR-A800 Instruction Manual (Detailed).)



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.



Use Pr.178 to Pr.189 (Input terminal function selection) to assign the terminals used for the X10 (X11) signal. (Refer to the FR-A800 Instruction Manual (Detailed).)

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.



Assign the IPF signal to a terminal on the FR-HC2. (Refer to the Instruction Manual of the FR-HC2.)



Always connect terminal RDY on the FR-HC2 to a terminal where the X10 signal or MRS signal is assigned on the inverter. Always connect terminal SE on the FR-HC2

to terminal SD on the inverter. Not connecting these terminals may damage the FR-HC2.



Always connect terminals R/L1, S/L2, and T/L3 on the FR-HC2 to the power supply. Operating the inverter without connecting them will damage the FR-HC2.



Do not install an MCCB or MC across terminals (R/L1, S/L2, T/L3) on the reactor 1 and terminals (R4/L14, S4/L24, T4/L34) on the FR-HC2. Doing so disrupts proper

operation.



Securely perform grounding (earthing) by using the grounding (earthing) terminal.



Installation of a fuse is recommended. (Refer to the Instruction Manual of the FR-HC2.)



Outside box is not available for the FR-HC2-H280K or higher. Connect filter capacitors, inrush current limit resistors, and magnetic contactors. (Refer to the Instruction

Manual of the FR-HC2.)

NOTE

• The voltage phases of terminals R/L1, S/L2, and T/L3 and the voltage phases of terminals R4/L14, S4/L24, and T4/L34 must be matched.

• The control logic (sink logic/source logic) of the high power factor converter and the inverter must be matched. (Refer to the FR-A800 Instruction Manual (Detailed).)
