Connection Of The High Power Factor Converter (Fr-Hc2) - Mitsubishi Electric FR-A800 Series Instruction Manual

NOTE
• The wiring distance between the inverter, brake unit, and discharging resistor must be within 2 m. Even when the cable is
twisted, the wiring length must be within 5 m.
• If the transistors in the brake unit should become faulty, the resistor will overheat and result in a fire. Install a magnetic
contactor on the inverter's input side and configure a circuit that shut off the current in case of a fault.
• Do not remove the jumper across terminals P/+ and P1 except when connecting a DC reactor (FR-HEL).
2.10.5 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.
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 "2 or 102" in Pr.30 Regenerative function
selection. (Refer to
Three-phase
AC power
supply
*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
*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/+ (P3)
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 Terminal P3 is equipped in the FR-A820-00770(15K) to 01250(22K), and FR-A840-00470(18.5K) to 01800(55K). When connecting multiple
inverters in parallel, always use either terminal P/+ or P3 for the connection. (Do not use terminals P/+ and P3 together.)
*4 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
*5 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.
*6 Use Pr.178 to Pr.189 (Input terminal function selection) to assign the terminals used for the X10 (X11) signal. (Refer to
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.
*7 Assign the IPF signal to a terminal on the FR-HC2. (Refer to the Instruction Manual of the FR-HC2.)
*8 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.
*9 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.
*10 Securely perform grounding (earthing) by using the grounding (earthing) terminal.
*11 Installation of a fuse is recommended. (Refer to the Instruction Manual of the FR-HC2.)
*12 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.)
