3.7.4 Connection of the high power factor converter FR-HC
When connecting the high power factor converter (FR-HC) to suppress power harmonics, perform
wiring securely as shown below.
ī
Keep input terminals (R/L1, S/L2, T/L3) open. Incorrect connection will damage the inverter.
ī
Do not insert an MCCB between the terminals P/+ and N/ā (between P and P/+, between N and
N/ā). Opposite polarity of terminals N/ā, P/+ will damage the inverter.
ī
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).
ī
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.
b
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 except when connecting a DC reactor.
