Switching Outputs - ABB F2 63A 230V CM4 Montageanleitung

2.3. Switching Outputs

The F2 ... 230V CM4 is equipped with 3 relay outputs (normally open contacts) which signal the
relevant status of the RCCB. It is possible to switch smaller loads directly via the relay contacts or, in
the case of bigger loads, with the aid of installation relays.
!
All relays have a common pole shared with terminal 8 and must be wired with the same potential.
The return signal for the toggle positions is produced via the terminals:
► Feedback signal "connected" (terminal 5)
This contact is closed if the monitored RCCB is connected or if the F2 ... 230V CM4 is not being
supplied with power.
► Feedback signal "disconnected" (terminal 6)
This contact is closed if the monitored RCCB is connected.
► Feedback signal "tripped" (terminal 7)
This contact is closed if the monitored RCCB has tripped.
► Common pole (terminal 8)
This terminal is the shared reference point of terminals 5-7.
In addition the F2 ... 230V CM4 has a relay output (changeover contact) which signals the blocked
status of the F2 ... 230V CM4. It is possible to switch smaller loads directly via this contact or, in the
case of bigger loads, with the aid of installation relays (see "Wiring", p. 22).
► Terminal 12: common pole
This terminal is the shared reference point of terminals 13 and 14.
► Terminal 13: "blocked" (NC)
This contact is closed if an automatic reconnection attempt has failed and the remote actuator is
subsequently blocked or if the F2 ... 230V CM4 is not being supplied with power.
Note: If the F2 ... 230V CM4 is in the "blocked" status then standards stipulate that the cause must be
identified. The RCCB and system must be checked accordingly.
► Terminal 14: "not blocked" (NO)
This contact is closed if all previous connection attempts have been able to be carried out without any
trouble.
Note: If the power supply of the F2 ... 230V CM4 fails then the "connected" and "blocked" relay contacts
will close. If the switching status of the RCCB is undefined then the "connected" and "disconnected"
relay contacts will switch alternately in a 1-s cycle.
