Sakset fra deres manual, Fronius anbefaler type B i sidste liniekovas skrev:Hej Zarge.
Jeg kunne nu ikke finde på at skifte fejlstrømsrelæ selv. Andre installationer er jeg ikke helt afvisende overfor at rode med. Men det letteste er vel bare at kontakte leverandøren.
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.
