2.9.4
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, set "rated motor voltage" in Pr.19 Base frequency voltage (under V/F control) or
Pr.83 Rated motor voltage (under other that V/F control) and "2" in Pr.30 Regenerative function selection.

supply

Do not connect anything to power input terminals (R/L1, S/L2, T/L3). Incorrect connection will damage the inverter. (E.OPT (option fault) will
occur.)

Remove the jumper across terminals P/+ and P1.

Do not install an MCCB across 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.

Use Pr.178 to Pr.189 (input terminal function selection) to assign the terminals used for the X10 (X11) 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 a terminal where the X10 signal or MRS signal is assigned in the inverter. Always connect 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.
 Installation of a fuse is recommended. (Refer to the Instruction Manual of 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
36.)
• For the parameter details, refer to the FR-F800 Instruction Manual (Detailed).
