(3) Connection of the high power factor converter (FR-HC)
(In the case of single-phase power input, the FR-HC cannot be connected.)
When connecting the high power factor converter (FR-HC) to suppress power supply
harmonics, perform wiring securely as shown below. Wrong connection will damage the
high power factor converter and inverter.

supply
Note: 1. Use sink logic (factory setting) when the FR-HC is connected. The FR-HC
cannot be connected when source logic is selected.
2. The power input terminals R, S, T (L
Incorrect connection will damage the inverter. Reverse polarity of terminals
N (-), P (+) will damage the inverter.
3. The voltage phases of terminals R, S, T (L
T4 must be matched before connection.
4. The MRS terminal functions can be changed using Pr.183 "MRS terminal
function selection". When connecting the high power factor converter (FR-
HC), use the inverter with "6" (factory-set) in Pr.183. (Refer to page 161.)
5. If the load capacity is less than half of the high power factor converter
capacity, satisfactory harmonic suppression effects cannot be produced.
6. Do not install the NFB between terminals P-N (P (+) -P, N (-) -N).
(4) Connection of the power factor improving DC reactor (FR-BEL)
Connect the FR-BEL power
factor improving DC reactor
between terminals P1-P (+).
In this case, the jumper
connected across terminals
P1-P (+) must be removed.
Otherwise, the reactor will
not function.
Note: 1. The wiring distance should be within 5m.
2. The size of the cables used should be equal to or larger than that of the
power supply cables (R (L
