Connection of stand-alone option units
2.10.2
Connection of the high power factor converter
(FR-HC2)
When connecting the high power factor converter (FR-HC2) to suppress power harmonics, perform wiring securely as shown
below. 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.


Remove jumpers installed in terminals R1/L11 and S1/L21 of the inverter, and connect the power supply for the control circuit to terminals
R1/L11 and S1/L21.

The voltage phases of terminals R4/L14, S4/L24, and T4/L34 and the voltage phases of terminals R/L1, S/L2, and T/L3 must be matched.

Do not install an MCCB across the terminals P/+ and N/- (across terminals P and P/+ or across N and N/-). Connecting the opposite polarity
of terminals N/- and P/+ will damage the inverter.
When using the FR-HC2 with the FR-A802 series, installation of a fuse is not required.

Change the FR-HC2 parameter setting to Pr.10 RDY signal logic selection = "0" (positive logic).

Use Pr.178 to Pr.189 (input terminal function selection) to assign the terminals used for the X10 signal.
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 an FR-HC2 terminal. (Refer to the Instruction Manual of FR-HC2.)

Always connect the FR-HC2 terminal RDY to the inverter terminal MRS(X10), and the FR-HC2 terminal SE to the inverter terminal SD. Not
connecting these terminals may damage the FR-HC2.

Always connect the R/L1, S/L2, and T/L3 terminals of FR-HC2 to the power supply. Operating the inverter without connecting them will
damage the FR-HC2.

Do not install an MCCB or MC between the reactor 1 terminals (R/L1, S/L2, T/L3) and the FR-HC2 terminals (R4/L14, S4/L24, T4/L34). It
will not operate properly.
 Securely perform grounding (earthing) by using the grounding (earthing) terminal.
 The number of connected peripheral devices differs according to the capacity. For the detail, refer to the FR-HC2 Instruction Manual.
