Regarding the installation of the reactor
When the inverter is installed near a large-capacity power transformer (500kVA or
more with the wiring length of 10m 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 reactor (FR-HEL(-H) /FR-BEL(-H)
or FR-HAL(-H)/FR-BAL(-H)).
•
Three-phase power input
•
Single phase power input
REMARKS
*When connecting the FR-HEL(-H)/FR-BEL(-H), remove the jumper across terminals P-P1.
The wiring length between the FR-HEL(-H)/FR-BEL(-H) and the inverter should be 5m
maximum and as short as possible.
Use the cables which are equal in size to those of the main circuit. (Refer to page 8)
The single-phase 100V power input model does not allow the DC reactor to be fitted.
