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.
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.

Keep input terminals (R/L1, S/L2, T/L3) open. Incorrect connection will damage the inverter.
Do not insert an MCCB between the terminals + and − (between P and +, between N and
−). Opposite polarity of terminals −, + will damage the inverter.
Use Pr. 178 to Pr. 184 "Input terminal function selection" to assign the terminals used for
the X10, RES signal. (Refer to section 6.10).
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.
The voltage phases of terminals R/L1, S/L2, T/L3 and terminals R4, S4, T4 must be
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 + and P1 except when connecting a DC reactor.
