( 3 ) Connection of the FR-HC high power factor converter (option unit)
(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
harmonics, wire as shown below. Wrong connection will damage the high power factor
converter and inverter.

Note: 1. The power input terminals R, S, T (L
Incorrect connection will damage the inverter. Reverse polarity of terminals
N (−), P (+) will damage the inverter.
2. The voltage phases of terminals R, S, T (L
T4 must be matched before connection.
3. If the load capacity is less than half of the high power factor converter
capacity, satisfactory harmonic suppression effects cannot be produced.
( 4 ) Connection of the power factor improving DC reactor (option)
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
