Connection Of The Power Regeneration Common Converter (Fr-Cv)(01160 Or Less) - Mitsubishi Electric FR-F740-00023 Instruction Manual

2.4.5 Connection of the power regeneration common converter (FR-CV)(01160 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 page 102.)

*1 Remove the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 of the inverter, and connect the
control circuit power supply across terminals R1/L11-S1/L21. Always keep the power input terminals R/
L1, S/L2, T/L3 open. Incorrect connection will damage the inverter. (E.OPT (option fault) will occur. (Refer
to page 278.))
*2 Do not insert an MCCB between the terminals P/+
Opposite polarity of terminals N/-, P/+ will damage the inverter.
*3 Assign the terminal for X10 signal using any of Pr. 178 to Pr. 189 (input terminal function selection).
(Refer to page 110)
*4 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.
*5 Be sure to connect terminal RDYB of the FR-CV to the X10 signal or MRS signal assigned terminal of the
inverter, and connect terminal SE of the FR-CV to terminal SD of the inverter. Without proper connecting,
FR-CV will be damaged.
CAUTION
The voltage phases of terminals R/L
Use sink logic when the FR-CV is connected. The FR-CV cannot be connected when source logic (initial setting) is
selected.
Do not remove a jumper across terminal P/+ and P1.
