2.8.5 Line connection via a ground-fault circuit interrupter
In addition to protection measures against hazardous shock current (e.g. overcurrent trip),
selectively tripping AC/DC-sensitive residual-current circuit-breakers can be used.
Note
A direct connection to a power system with selectively tripping AC/DC-sensitive residual-
current circuit-breakers is only possible with the 5 kW, 10 kW, 16 kW and 36 kW Line
Modules because suitable residual-current devices with higher ratings are not available as
qualified products.
Selectively tripping AC/DC-sensitive residual-current circuit-breakers can be used without
restriction in the event of a fault as a protective measure against hazardous shock currents.
