3.6.4 Connection of the high power factor converter FR-HC
When connecting the high power factor converter (FR-HC) to suppress power harmonics, per-
form wiring securely as shown below.
Keep input terminals (R/L1, S/L2, T/L3) open. Incorrect connection will damage the inverter.
Do not insert an MCCB between the terminals P/+ and N/– (between P and P/+, between
N and N/–). Opposite polarity of terminals N/–, P/+ will damage the inverter.
Use Pr. 178 to Pr. 182 to assign the terminals used for the X10, RES signal.
Be sure to connect terminal RDY of the FR-HC to the X10 signal or MRS signal assigned
terminal of the inverter, and connect terminal SE of the FR-HC to terminal SD of the inverter.
Without proper connecting, FR-HC will be damaged.

CAUTION:
Perform wiring of the high power factor converter (FR-HC) securely as shown below.
Incorrect connection will damage the high power factor converter and inverter.

NOTES
The voltage phases of terminals R/L1, S/L2, T/L3 and terminals R4, S4, T4 must be
matched.
Use sink logic when the FR-HC is connected. The FR-HC cannot be connected when
source logic (factory setting) is selected.
Do not remove a jumper across terminal P/+ and P1.
