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

When connecting the power regeneration common converter (FR-CV), connect the inverter terminals (+ and -) and power
regeneration common converter (FR-CV) terminals as shown below so that their symbols match with each other.
MCCB
Three-phase
AC power supply
∗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 + and - (between P/L+ and +, between N/L- and -). Opposite polarity of terminals - and +
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 MRS, RES signal. (Refer to page 108)
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 when the FR-CV is connected. The FR-CV cannot be connected when source logic (factory setting) is
selected.
Do not remove a jumper across terminal + and P1.
2.4.5

Connection of a DC reactor (FR-HEL)

When using the DC reactor (FR-HEL), connect it across terminals + and P1.
In this case, the jumper connected across terminals + and P1 must be removed. Otherwise, the reactor will not exhibit its
performance.
NOTE
The wiring distance should be within 5m.
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 16)
