Connection Of The High Power Factor Converter (Fr-Hc2) - Mitsubishi Electric FR-CS82S-025 Instruction Manual

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.
Three-phase
AC power supply
*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
*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.)
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).
