NOTE! A residual current circuit breaker for the AC connecting cable may be re-
quired depending on local regulations, the power supply company as well as oth-
er conditions. A type A residual current circuit breaker with a trip current of at least
100 mA is generally sufficient in this case. Nevertheless, false alarms can be trig-
gered for the type A residual current circuit breaker in individual cases and de-
pending on local conditions.
For this reason, Fronius recommends that you use a residual current circuit
breaker suitable for a frequency converter.
