NOTE! Local regulations, the energy supply company or other factors may re-

quire an earth-leakage circuit breaker in the grid line. For this situation, a type A

earth-leakage circuit breaker with a tripping current of at least 100 mA is generally

adequate. In particular cases, and depending on local factors, however, the type

A earth-leakage circuit breaker may trip at the wrong time. For this reason, Fron-

ius recommends that an earth-leakage circuit breaker that is suitable for frequen-

cy converters should be used.
