Page 32 Peripheral Devices ! Countermeasures • If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of the inverter. Note that motor noise increases. • Using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and other line, operation can be performed with the carrier frequency kept high (with low noise).
Page 33 Peripheral Devices (3) Selecting the rated sensitivity current for the earth (ground) leakage breaker CAUTION •On the power receiving side, install a no-fuse breaker (NFB) to protect the primary wiring of the inverter. Selection of NFB depends on the power supply side power factor (which changes with the power supply voltage, output frequency and load) of the inverter.
Page 34 Peripheral Devices CAUTION •The earth (ground) leakage circuit breaker should be installed to the primary (power supply) side of the inverter. •In the connection neutral point grounding system, the sensitivity current becomes worse for earth (ground) faults in the inverter secondary side.

Peripheral Devices 1.10.5 Regarding noises and the installation of the noise filter Some noises enter the inverter causing it to malfunction and others are generated by the inverter causing peripheral devices to malfunction. Though the inverter is designed to be insusceptible to noises, it handles low-level signals, so it requires the following general countermeasures to be taken.
