Mitsubishi Electric FR-A800 Series Instruction Manual page 107

After making sure that the wiring is correct and secure, set "2 or 102" in Pr.30 Regenerative function selection. (Refer to
page 724.)

*1 Never connect the power supply to terminals R/L1, S/L2, and T/L3 on the inverter. Doing so will damage the inverter and the converter.
*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-XC is connected, the jumper across terminals P/+ and P1 does not affect the function. (The FR-XC can be connected with the
jumper connected.) Refer to
*5 Connect between the inverter terminal P/+ and the converter terminal P/+ and between the inverter terminal N/- and the converter terminal N/-
for polarity consistency.
Connecting opposite polarity of terminals P/+ and N/- will damage the converter and the inverter.
*6 Confirm the correct phase sequence of three-phase current to connect between the reactor and the converter, and between the power supply
and terminals R/L1, S/L2, and T/L3.
Incorrect connection will damage the converter.
*7 Be sure to connect the power supply and terminals R/L1, S/L2, and T/L3 of the converter. Operating the inverter without connecting them will
damage the converter.
*8 Assign the X10 signal to any of the input terminals.
*9 To use separate power supply for the control circuit, remove each jumper at terminal R1/L11 and terminal S1/L21.
*10 Install UL listed fuses on the input side of the reactor to meet the UL/cUL standards (refer to the FR-XC Instruction Manual for information about
the fuse).
