Installation sequence
36
1. Make sure that the miniature circuit breaker and the
residual current operated circuit breaker (FI-A/RCCB)
are installed and connected according to the
manufacturer's instructions.
2. Install the SR on the DIN rail directly next to the RCD
switch and connect the brackets mechanically via
the integrated pin ⑧ of the SR.
3. Connect the supply cable of the AC/DC power supply
unit according to the figure and the manufacturer's
instructions.
4. Remove the four-pole screw-type terminal connector
① from the PCB using a suitable tool (e.g. curved
snipe nose pliers) ②.
5. Connect pin ③ of the SR by means of the control
line to the AC/DC power supply unit output (+24V).
6. Connect pin ④ of the SR by means of the control
line. Connect the AC/DC power supply unit output
(0V) via the control line and guide both cables
through the sealing element ⑤.
7. Connect the other two ends of the control lines to
the contacts 1.3 ⑥ and 1.4 ⑦ of the four-pole
screw-type terminal connector ①. Make sure that
you connect the correct pins 1.3 and 1.4.
8. Place the four-pole screw-type terminal connector ①
back to its original location on the PCB using a
suitable tool (e.g. curved snipe nose pliers) ②.
9. The contact between ⑥ and ⑦ is closed in the event
of a malfunction of the wallbox output relays, which
activates the SR and thus trips the RCD switch.
Note:
* Sample components
The components shown here are recommendations
that can be replaced with devices that have the same
properties. Technical documentation of the compo-
nent manufacturer must be observed.
Note:
** Multiple current releases
Several shunt releases can be supplied via one AC/DC
power supply unit, see specification of the compo-
nents used.
