1.2.7 Regarding the installation of the power factor
improving reactor
When the inverter is installed near a large-capacity power transformer (500kVA or
more with the wiring length of 10m (32.81feet) or less) or the power capacitor is to be
switched, an excessive peak current will flow in the power supply input circuit,
damaging the converter circuit. In such a case, always install the power factor
improving reactor (FR-BEL(-H) or FR-BAL(-H)).
REMARKS
*When connecting the FR-BEL(-H), remove the jumper across terminals P-P1.
The wiring length between the FR-BEL(-H) and the inverter should be 5m(16.40feet)
maximum and as short as possible.
Use the cables which are equal in size to those of the main circuit. (Refer to page 8)
