Connection Of The High Power Factor Converter (Fr-Hc2) (Standard Model / Ethernet Model) - Mitsubishi Electric 800 Series Instruction Manual

 Connection example with the FR-BR(-H) resistor unit
MCCB
Three phase AC
power supply
*1 When wiring, make sure to match the terminal symbols (P/+, N/-) on the inverter and on the brake unit (FR-BU2). (Incorrect connection will
damage the inverter and brake unit.)
*2 When the power supply is 400 V class, install a stepdown transformer.
*3 The wiring distance between the inverter, brake unit (FR-BU2) and resistor unit (FR-BR) must be within 5 m. When using twisted pair cable, use
the cable within 10 m.
*4 The contact between TH1 and TH2 is closed in the normal status and is open at a fault.
NOTE
• Do not remove the jumper across terminals P/+ and P1 except when connecting a DC reactor (FR-HEL).
2.9.3 Connection of the high power factor converter (FR-
HC2) (Standard model / Ethernet model)
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.
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 set "0 (initial value)" or "2" (when the automatic
restart after instantaneous power failure is selected) in Pr.30 Regenerative function selection. (Refer to the FR-E800
Instruction Manual (Function).)
MCCB MC
Three-phase
AC power
supply
*1 Do not connect anything to power input terminals (R/L1, S/L2, and 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 and RES signals. (Refer to the FR-E800
Instruction Manual (Function).)
*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.
