Connection Of The Power Regeneration Common Converter (Fr-Cv) (Standard Model / Ethernet Model) - Mitsubishi Electric 800 Series Instruction Manual

*5 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.
*6 Do not connect anything to terminal P4.
*7 Assign the X10 signal to any of the input terminals.
*8 To use separate power supply for the control circuit, remove each jumper at terminal R1/L11 and terminal S1/L21.
*9 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).
*10 Do not install an MCCB or MC between the reactor and the converter. Doing so disrupts proper operation.
CAUTION
• In the common bus regeneration mode, always connect between the converter terminal RYB and the inverter terminal
to which the X10 (MRS) signal is assigned and between the converter terminal SE and the inverter terminal SD. Failure
to do so will damage the converter.
NOTE
• Configure a system so that the magnetic contactor at the converter input side shuts off the power supply at a failure of the
converter or the connected inverter. (The converter does not shut off the power supply by itself.) Failure to do so may overheat
and burn the resistors in the converter and the connected inverter.
• The safety communication model (FR-E800-SCE) is not intended for the use with the multifunction regeneration converter (FR-
XC) except when the converter is used in power regeneration mode.
• For details on model selection and connection, refer to the FR-XC Instruction Manual.
• For details on connection in common bus regeneration mode with harmonic suppression enabled or in power regeneration
mode 2, refer to the FR-XC Instruction Manual.
2.9.5 Connection of the power regeneration common
converter (FR-CV) (Standard model / Ethernet
model)
When wiring for connecting the power regeneration common converter (FR-CV) to the inverter, make sure to match the terminal
symbols (P/+, N/-) on the inverter and on the power regeneration common converter.
After making sure that the wiring is correct and secure, 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).)

supply
*1 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 the FR-E800 Instruction Manual (Maintenance).)
*2 When the FR-CV is connected, the jumper across terminals P/+ and P1 does not affect the function. (The FR-CV can be connected with the
jumper connected.)
*3 Do not install an MCCB across terminals P/+ and N/- (between terminals P/L+ and P/+ or between N/L- and N/-). Connecting the opposite polarity
of terminals N/- and P/+ will damage the inverter.
*4 Use Pr.178 to Pr.182 (Input terminal function selection) to assign the terminals used for the X10 signal. (Refer to the FR-E800 Instruction
Manual (Function).)
*5 Be sure to connect the power supply and terminals R/L11, S/L21, and T/MC1. Operating the inverter without connecting them will damage the
power regeneration common converter.
