Connection of the high power factor converter (FR-HC, MT-HC)

When connecting the high power factor converter (FR-HC) to suppress power harmonics, per-
form wiring securely as shown below.
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.
After making sure that the wiring is correct, set "2" in Pr. 30 "Regenerative function selection"
(Refer to section 6.13.2.)
Connection with the FR-HC (01800 or less)
3-phase AC
power supply

Remove the jumpers across the inverter terminals R/L1-R1/L11, S/L2-S1/L21, and connect
the control circuit power supply to the R1/L11 and S1/L21 terminals. Always keep the power
input terminals R/L1, S/L2, T/L3 open. Incorrect connection will damage the inverter. (E.OPT
(option alarm) will occur. (Refer to page 7-16.)
Do not insert the MCCB between terminals P/+-N/− (P/+-P/+, N/−-N/−). Opposite polarity of
terminals N/−, P/+ will damage the inverter.
Use Pr. 178 to Pr. 189 "input terminal function selection" to assign the terminals used for
the X10 (X11) signal. (Refer to section 6.14.1.)
For communication where the start command is sent only once, e.g. RS-485 communication
operation, use the X11 signal when making setting to hold the mode at occurrence of an
instantaneous power failure. (Refer to section 6.13.2.)
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.
