<Example>
Note:1. The ground leakage circuit breaker should be installed to the primary (power
supply) side of the inverter.
2. Ground fault on the secondary side of the inverter can be detected at the
running frequency of 120Hz or lower.
3. In the 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)
4. 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, hysteresis
loss, and the temperature all increase.
5. 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
