2.4. Remote tripping
The F2 ... 230V CM4 is equipped with an internal test resistor which is provided with a residual current
of I
= 500 mA for a remote tripping of a RCCB.
∆n
The terminals must be connected as follows (see "Wiring for Remote Trip Facility", p. 23):
► Remote trip facility Lx (Terminal 15)
Remote trip facility Lx is connected with a phase Lx switched by the RCCB.
► Remote trip facility N (Terminal 16)
Remote trip facility N is connected with the unswitched neutral wire on the input side of the RCCB.
Note: If the remote tripping is intended to be carried out with a nominal residual current I
connected RCCB (simulation of the test button activation), then in this case the optionally available
resistor cable for 300 mA, 100 mA or 30 mA must be used. Otherwise the testing will be carried out
using 500 mA.

Operating Instructions
3.1. Rotary Switch Settings
Three operating modes and the number of reconnection attempts for the F2 ... 230V CM4 can be
selected with the rotary switch on the enclosure cover:
► Operating mode ON
The F2 ... 230V CM4 is switched on and carries out the control commands which are activated via the
signal inputs. The status LED is permanently illuminated.
► Operating mode AUTO 1x / AUTO 3x
The F2 ... 230V CM4 is switched on and carries out the control commands which are activated via
the signal inputs. The status LED is permanently illuminated. If automatic reconnection is required
then for safety reasons we recommend that the number of reconnection attempts should be set to
1x using the rotary switch on the enclosure cover. However, if several reconnection attempts are
needed in the system then the number may be increased to 3x. In each case these will be carried
out 15 seconds after tripping. Within this period, flash code 3 will be signalled via the status LED
(see "Flash Codes", p. 21), in order to indicate the imminent connection attempt.
!
Risk of crushing on automatic connection!
If the RCCB has not been switched on within five seconds of the last reconnection attempt, i. e.
the fault in the RCCB's circuit is still present, no further attempts at reconnection will be made. The
F2 ... 230V CM4 will be blocked and will not carry out any more control commands, which will be
indicated using flash code 4. In order to cancel the blocking, the F2 ... 230V CM4 must briefly be
reset using the rotary switch (RESET). A brief interruption in the power supply will not be sufficient
