2.1. Power Supply
The DFA is equipped with a voltage of 230 V
AC
. The permitted tolerance amounts to ± 15%
►
AC (Terminals 9 + 10)
The 230-V
AC
power supply is connected to these terminals
2.2. Control inputs
The wide range inputs (connecting, disconnecting, tripping) are connected via buttons with a voltage
of max. 230 V
UC
.
!
All three control inputs must be wired with the same potential. A combination of e.g. 230 V
AC
and
24 V
AC
is not permitted. Only buttons may be connected to the control inputs.
►
Connecting (Terminal 1)
A short operating pulse at this input results in the flange-mounted RCCB being switched on. If it is
already connected, no switching will occur.
►
Disconnecting (Terminal 2)
If a short operating pulse is given at this input, the mounted RCCB will be switched off, provided it has
not already been disconnected.
►
Tripping (Terminal 3)
A short operating pulse at this input results in a test residual operating current I
∆
being transmitted
briefly to the connected RCCB which should cause the latter to trip during this time. However, the
RCCB must have been connected beforehand otherwise there will be no reaction to the input signal.
►
Common pole (terminal 4)
In this case the negative pole will be connected when operating with direct current. The neutral wire
must be connected when operating with mains voltage. If the RCCB does not trip (toggle of the RCCB
not in central position) the status LED will signal flash code 2 (see “Flash Codes”, p. 21). This can
only be reset by briefly switching the DFA off with the rotary switch on the enclosure cover (RESET) or
by disconnecting the DFA from the operating voltage for a short time.
!
After an unsuccessful tripping attempt, a further tripping attempt should not be made – as would
be the case with a normally operated RCCB – until after approx. 30 seconds, so that the DFA test
circuit is not overloaded.
On initial commissioning of the DFA the function of the remote tripping must be tested in order to make
sure that the wiring between the RCCB and DFA is not incorrect and that the RCCB is not defective. A
suspected defect in the RCCB may also be checked by pressing the test button on the RCCB.
Note: If e.g. a continuous signal is produced at the control inputs due to a blocked button, then the
corresponding function will be carried out once. All other functions may continue to be used.
