2.4.4 Connection of the power regeneration common converter (FR-CV)
When connecting the power regeneration common converter (FR-CV), connect the inverter terminals (P/+ and N/-) and power
regeneration common converter (FR-CV) terminals as shown below so that their symbols match with each other.
2.4.5 Connection of a DC reactor (FR-HEL)
When using the DC reactor (FR-HEL), connect it across terminals P/+ and P1.
In this case, the jumper connected across terminals P/+ and P1 must be removed. Otherwise, the reactor will not exhibit its
performance.
∗1 Always keep the power input terminals R/L1, S/L2, T/L3 open. Incorrect connection will damage the inverter.
∗2 Do not insert an MCCB between the terminals P/+ and N/- (between P/L+ and P/+, between N/L- and N/-). Opposite polarity of terminals
N/- and P/+ will damage the inverter.
∗3 Always 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.
∗4 Use Pr. 178 to Pr. 182 (input terminal function selection) to assign the terminals used for the X10, RES signal. (Refer to page 113)
∗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.
NOTE
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 (factory setting) when the FR-CV is connected. The FR-CV cannot be connected when source logic is
selected.
Do not remove a jumper across terminal P/+ and P1.
NOTE
The wiring distance should be within 5m (16.4feet).
The size of the cables used should be equal to or larger than that of the power supply cables (R/L1, S/L2, T/L3). (Refer
to page 17)
