Mitsubishi Electric FR-A500 Instruction Manual page 40

Note: 1. Do not insert MCCB between terminals P-N <+ - –> (P/+ -P<+ - P>, N/– - N < – -N>).
2. Remove the jumpers across terminals R-R1 and S-S1 <L
connect the control circuit power supply across terminals R1
terminals R, S, T <L
Opposite polarity of terminals N <->, P <+> will also damage the inverter.
3. The voltage phases of terminals R, S, T <L
before connection.
4. Use Pr. 180 to Pr. 186 (input terminal function selection) to assign the terminals used for the X10
and X11 signals.
Use the X11 signal when using the computer link plug-in option (FR-A5NR). (Refer to page 85)
5. When the FR-HC is connected, use sink logic (factory setting). For source logic, the FR-HC
cannot be connected. (For the EC version, select the sink logic.)
(5) 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. After making sure that the wiring is correct, set "2" in Pr. 30 "regenerative
function selection". For details, refer to the instruction manual of the FR-CV type power regeneration
common converter.

Note: 1. Remove the jumpers across the R-R1 <L1-L11> and S-S1 <L2-L21> terminals of the inverter,
and connect the control circuit power supply across terminals R1-S1 <L11-L21>. The power
input terminals R, S, T <L1, L2, L3> must be open. Accidental 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. 180 to Pr. 186 (input terminal function selection) to assign the terminals used for the X10
signal. (Refer to page 155.)
4. When the FR-CV is connected, use sink logic (factory setting). For source logic, the FR-CV
cannot be connected. (For the EC version, select the sink logic.)
5. Do not insert MCCB between terminals P-N <+ - –> (P/L+-P <P/L+ - +>, N/L– - N <N/L– - –>)
6. Make sure terminals R/L11, S/L21, T/MC1 are connected to the power supply. Running the
inverter without connecting the terminals will damage the power regeneration common converter.
