Connection Of The Power Regeneration Common Converter (Fr-Cv) - Mitsubishi Electric FR-S520E Series Instruction Manual

Connection to the stand-alone option
1.6.4 Connection of the power regeneration common
converter (FR-CV)
When connecting the FR-CV type power regeneration common converter, connect the
inverter terminals (P, N) and FR-CV type power regeneration common converter
terminals as shown below so that their signals match with each other.

CAUTION
1. Use sink logic (factory setting) when the FR-CV is connected. The FR-CV
cannot be connected when source logic is selected.
2. The power input terminals R, S, T must be open. Incorrect connection will
damage the inverter.
3. The voltage phases of terminals R/L11, S/L21, T/MC1 and terminals R2/L1,
S2/L2, T2/L3 must be matched before connection.
4. Use Pr. 60 to Pr. 63 (input terminal function selection) to assign the terminals
used for the RES and MRS signals.
5. Do not insert MCCB between terminals P-N (P/L+ - P, N/L− - N). Opposite
polarity of terminals N, P will damage the inverter.
6. Make sure to connect the terminal R/L11, S/L21, T/MC1 to the power supply.
Running the inverter without connecting the terminals will damage the
power regeneration common converter.
7. The N terminal is not provided for the FR-S520E-0.1K to 0.75K.
8. Do not remove a jumper across terminal P/+ and P1 except when connecting
a DC reactor.
