Mitsubishi Electric FR-F500 Series Instruction Manual page 38

Note: 1. Remove the jumpers across terminals R-R1 and S-S1 <L
connect the control circuit power supply to terminals R1-S1 <L
R, S, T < L
Accidental connection to these terminals will damage the inverter. Opposite polarity of terminals
N, P <−, +> will also damage the inverter.
2. Always match the voltage phases of terminals R, S, T < L
before making connection.
3. 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 82)
4. When connecting the FR-HC, use sink logic (factory setting). For source logic, the FR-HC cannot
be connected. (For the EC version, select the sink logic.)
5. Do not insert NFB between terminals P-N (P-P, N-N <+-P, −-N>).
(4) 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 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 power regeneration common converter.

terminals R/L
Opposite polarity of terminals N/−, P/+ will damage the inverter.
2. The voltage phases of terminals R/L
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 140.)
4. Do not insert NFB between terminals P-N (P/L+-P, N/L−-N)
5. Make sure terminals R/L
inverter without connecting these terminals will damage the power regeneration common
converter.
