NOTE!
Local regulations, the energy supply company or other factors may require a resid-
ual current protective device (RCD) in the AC connection lead.
For this situation, a type A residual-current circuit breaker is generally adequate. However,
in certain circumstances, and depending on local factors, the type A residual-current circuit
breaker may trip at the wrong time.
For this reason, Fronius recommends that a residual-current circuit breaker that is suitable
for frequency converters should be used.
