Connection Of The Power Regeneration Common Converter (Fr-Cv) - Mitsubishi Electric FR-C500 Instruction Manual

Connection of Stand-Alone Option Units
CAUTION
1. Always keep the power input terminals R, S and T open. Incorrect connection
will damage the inverter. Opposite polarity of terminals N/-, P/+ will damage the
inverter.
2. The voltage phases of terminals R, S, T and terminals R4, S4, T4 must be
matched before connection.
3. Use Pr. 60 to Pr. 63, Pr. 65 and Pr. 505 (input terminal function selection) to
assign the terminals used for the MRS and RES signals.
4. When the FR-HC is connected, use sink logic (factory setting). For source
logic, the FR-HC cannot be connected.
1.11.3 Connection of the power regeneration common
converter (FR-CV)
When connecting the FR-CV power regeneration common converter, connect the
inverter terminals (P/+, N/-) and FR-CV power regeneration common converter
terminals as shown below so that their symbols match with each other.

CAUTION
1. Always keep R/L1, S/L2 and T/L3 of the inverter open. Incorrect connection
will damage the inverter. Opposite polarity of terminals N/-, P/+ will damage
the inverter.
2. The voltage phases of terminals R/L11, S/L21, T/MC1 and terminals R2/L1,
S2/L2, T2/L3 must be matched before connection.
3. Use Pr. 60 to Pr. 63, Pr. 65 and Pr. 505 (input terminal function selection) to
assign the terminals used for the RES and MRS signals.
