2.10.5 Connection of the high power factor converter (FR- HC2) 1 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. 2 V/F control) or Pr.83 Rated motor voltage (under other than V/F control) and "2 or 102" in Pr.30 Regenerative function After making sure that the wiring is correct and secure, set the rated motor voltage in Pr.19 Base frequency voltage (under selection .
(Refer to page 743 .) 3 4 Three-phase AC power supply 5 6 7 *1 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 page 812 .)) *2 Instead of connecting the terminals to the AC power supply, the control circuit can be powered by connecting terminal R1/L11 to terminal P/+ and terminal S1/L21 to terminal N/-. In this case, do not connect the terminals to the AC power supply.
Doing so will damage the inverter. *3 When the FR-HC2 is connected, the jumper across terminals P/+ and P1 does not affect the function. (The FR-HC2 can be connected with the jumper connected (initial setting). Refer to page 56 for the jumper connection status in the initial setting.) *4 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. *5 Use Pr.178 to Pr.189 (Input terminal function selection) to assign the terminals used for the X10 (X11) signal.
(Refer to page 539 .) 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. *6 Assign the IPF signal to a terminal on the FR-HC2. (Refer to the Instruction Manual of the FR-HC2.) *7 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. *8 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.
*9 Securely perform grounding (earthing) by using the grounding (earthing) terminal. *10 Installation of a fuse is recommended. (Refer to the Instruction Manual of the FR-HC2.) *11 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.) 8 9 10 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 page 73 .) Do not connect a DC reactor (FR-HEL) to the inverter when the FR-HC2 is connected. Always connect terminal RDY on the FR-HC2 to a terminal where the X10 signal or MRS signal is assigned on the CAUTION inverter. Always connect terminal SE on the FR-HC2 to terminal SD on the inverter. Not connecting these terminals may damage the FR-HC2. 105 2.
