1.6.3 Installation of reactor
When the inverter is connected near a large-capacity power transformer (1000kVA or more and wiring length 10m
max.) 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 DC reactor or AC reactor (FR-HEL/BEL or
FR-HAL/BAL).
REMARKS
* When connecting the FR-HEL/BEL, remove the jumper across terminals P-P1.
The wiring length between the FR-HEL/BEL and inverter should be 5m maximum and minimized.
Use the same wire size as that of the power supply wire (R, S, T). ( Refer to the Instruction Manual (basic).)
