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
1
, L
2
, L
3
) must be open.
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
1
, L
2
, L
3
) and terminals R4, S4,
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.

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

)).
