2.8.2 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 follows. Incorrect connection will damage the high power factor converter and the inverter.
Reactor1 (FR-HCL21) Outside box （ FR-HCB2 ） Inverter High power factor converter (FR-HC2) Reactor2 (FR-HCL22) MCCB MC R4/L14 R2/ L12 R3/ L13 S3/ L23 T3/ L33 R/L1 *1 Motor S/L2 T/L3 Three-phase AC power supply S2/ L22 S4/L24 U V W IM T2/ L32 T4/L34 Fuse *8 Earth (ground) ROH2 ROH1 ROH SD P/+ P/+ N/- N/- *2 88R 88R 88S 88S RDY *4 *3 X10 *7 R/L1 S/L2 T/L3 *5 RSO SE SD RES *3 R1/L11 S1/L21 *7 *7 *1 Do not connect anything to power input terminals (R/L1, S/L2, T/L3). Incorrect connection will damage the inverter. *2 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. *3 Use Pr.178 to Pr.182 (Input terminal function selection) to assign the terminals used for the X10 signal or the RES signal. (Refer to page 142 ). *4 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. *5 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.
*6 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. *7 Securely perform grounding (earthing) by using the grounding (earthing) terminal. *8 Installation of a fuse is recommended. (Refer to the Instruction Manual of the FR-HC2.) • 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 36 ). 44 2.
