Connection Of The Power Regeneration Common Converter Fr-Cv - Mitsubishi Electric FR-A700 Instruction Manual

Wiring
3.8.5

Connection of the power regeneration common converter FR-CV (01800

or less)
When connecting the power regeneration common converter (FR-CV), make connection so that
the inverter terminals (P/+, N/−) and the terminal symbols of the power regeneration common
converter (FR-CV) are the same.
After making sure that the wiring is correct, set "2" in Pr. 30 "Regenerative function selection".
(Refer to section 6.13.2).

Remove the jumpers across the inverter terminals R/L1-R1/L11, S/L2-S1/L21, and connect
the control circuit power supply to the R1/L11 and S1/L21 terminals. Always keep the power
input terminals R/L1, S/L2, T/L3 open. Incorrect connection will damage the inverter. (E.OPT
(option alarm) will occur. (Refer to page 7-16.)
Do not insert the MCCB between terminals P/+-N/− (P/L+-P/+, N/L−-N/−). Opposite polarity
of terminals N/−, P/+ will damage the inverter.
Assign the terminal for X10 signal using any of Pr. 178 to Pr. 189 "input terminal function
selection". (Refer to section 6.14.1.)
Be sure to connect the power supply and terminals R/L11, S/L21, T/MC1. Operating the
inverter without connecting them will damage the power regeneration common converter.
NOTES
The voltage phases of terminals R/L11, S/L21, T/MC1 and terminals R2/L1, S2/L2, T2/L3
must be matched.
Use sink logic when the FR-CV is connected. The FR-CV cannot be connected when source
logic (factory setting) is selected.
