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.
