Connection of the power improving DC reactor FR-HEL

When using the DC reactor (FR-HEL), connect it between terminals P1-P/+. For the 01160 or
less, the jumper connected across terminals P1-P/+ must be removed. Otherwise, the reactor
will not exhibit its performance.
Remove the
NOTES The wiring distance should be within 5m.
The size of the cables used should be equal to or larger than that of the power supply cables
(R/L1, S/L2, T/L3). (Refer to page 3-12.)
For inverters ≥ 01800 the supplied DC reactor has to be installed to the mentioned terminals.

Installation of a reactor

When the inverter is connected near a large-capacity power transformer (1000kVA or more) or
when a power capacitor is to be switched over, an excessive peak current may flow in the power
input circuit, damaging the converter circuit. To prevent this, always install the optional DC re-
actor (FR-HEL) or AC reactor (FR-BAL-B).

When connecting the FR-HEL to the 01160 or less, remove the jumper across terminals
P-P1. For the 01800 or more, a DC reactor is supplied. Always install the reactor.
NOTES The wiring length between the FR-HEL and inverter should be 5m maximum and minimized.
Use the same wire size as that of the power supply wire (R/L1, S/L2, T/L3). (Refer to page 3-12).
