! Installation and selection of no-fuse breaker
Install a no-fuse breaker (NFB) in the power supply side for protection of the inverter's
primary wiring. Refer to the previous table and choose the NFB according to the
inverter's power supply side power factor (which changes with the power supply
voltage, output frequency and load). Especially for a completely electromagnetic type
NFB, the one with a larger capacity must be selected since its operational
characteristics change with harmonic currents. (Check the data of the corresponding
breaker for confirmation.) Also, the earth leakage circuit breaker used should be
durable against harmonic/surge (such as Progressive Super Series).

Note:1. The power factor may be slightly lower.
When the inverter is connected near a large-
capacity power supply transformer (500kVA
or more, wiring length 10m maximum) or
there is power capacitor switch-over,
excessive peak currents may flow into the
power input circuit and damage the converter
circuit. In such a case, the power supply
improving reactor (FR-BEL or FR-BAL) must
be installed.
