Main circuit terminals

CAUTION

The ground leakage circuit breaker should be installed to the primary (power supply) side of the inverter.

In the Manual background connection neutral point grounded system, the sensitivity current becomes worse for ground faults on the inverter secondary side. Grounding must conform to the requirements of national and local safety regulations and electrical codes. (JIS, NEC section 250, IEC 536 class 1 and other applicable standards)

When the breaker is installed on the secondary side of the inverter, it may be unnecessarily operated by harmonics if the effective value is less than the rating. In this case, do not install the breaker since the eddy current and hysteresis loss increase and the temperature rises.

General products indicate the following models: BV-C1, BC-V, NVB, NV-L, NV-

G2N, NV-G3NA, NV-2F, ground leakage relay (except NV-ZHA), NV with AA neutral wire open-phase protection

The other models are designed for harmonic and surge suppression: NV-C/ NV-S/MN series, NV30-FA, NV50-FA, BV-C2, ground leakage alarm breaker (NF-Z), NV-ZHA, NV-H
