1.6.5 Connection of the power regeneration common
converter (FR-CV)
When connecting the power regeneration common converter (FR-CV), connect the
inverter terminals (P/+, N/-) and power regeneration common converter (FR-CV)
terminals as shown below so that their symbols match with each other.
*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/+-N/- (between P/L+-P/+, between
N/L--N/-). Opposite polarity of terminals N/-, P/+ will damage the inverter.
*3. Use Pr. 60 to Pr. 63 (input terminal function selection) to assign the terminals used
for the MRS, RES signal.
*4. 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.
*5. Be sure to connect terminal RDYB of the FR-CV to the 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/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.
•Do not connect the filter pack.
