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 is generally sufficient in this
case. However, false alarms can be triggered for the residual current circuit
breaker in individual cases and depending on local conditions. For this reason,
Fronius recommends that you use a residual current circuit breaker suitable for a
frequency converter.
NOTE! Three-phase inverters only: When using a residual current circuit breaker,
the voltage difference between the PE grounding conductor and the N neutral
conductor cannot be higher than 8 V.
