Detailed description in the Design Engineer's manual.
(3)
Locking Function available via Ekip Connect.
(4)
Not active for voltages <30V and if the circuit-breaker is open. The protection is also active for negative (reverse) active power, but it is
independent of the RP protection (Protection against reverse active power).
