Remote Switching Protection
Remote Switching Protection (RSP) prevents the opening/closing of the circuit breaker
via the communications interface by means of an open/close command. Remote
Switching Protection uses two terminals on the X61 connector. It is connected to the
communications module with role A and is then effective for communications module A
and optionally also for a second communications module B.
Remote Switching Protection is active by default and must be deliberately deactivated.
The connection (RSP) must be bridged for deactivation.
