The Protection Conductor Circuit (Pe) For Grounding; Ct02 Power Supply Circuit; General Load Connecting Circuit; Connecting Circuit Of A 12Vdc Solenoid Valve - Favero CT02 Manual De Instalación

The circuits are as follows :
3.1 The protection conductor circuit (PE)
for grounding
The protection conductor (PE) for grounding must
not have a cross section inferior to that of the other
conductors entering the CT02.
C onnect the grounding conductor to the appropriate
ring terminal provided, as indicated in Fig. 3 . The
terminal provided is suitable for cables with cross
sections of 2.5–6 mm

3.2 CT02 power supply circuit

The CT02 requires a power supply as indicated in
Chapter 1.3.
1) Power supply 100-230V.
2) Connection of the 12Vdc to the CT02.
Fig. 3: Electrical connections on the power supply
device provided with the CT02.
Place the provided power supply device inside an
electrical panel, following the regulations in effect in
the country in which installation takes place. For
example the IEC60364-7 requires a distance of at
least 3 m from the shower tray (Fig. 1) or at least
3.6 m from the small shower for hobless showers
(Fig. 2).
For connections on the power supply 12Vdc placed
inside the electrical panel:
1) See Fig. 3.
2) Use the appropriate terminal forks provided,
which are suitable for use with cables with
cross sections of 0.5 – 1.5 mm
3) Connect the power supply conductors to the
terminals L and N of the power supply
device using
terminal forks suitable for cables with cross
sections of 0.5-1.5 mm
4) To interrupt the supply of power to the CT02
use a 6A double pole residual circuit breaker
with overload protection and with threshold
current Idn= 30 mA .
5) To connect the power supply device's 12Vdc
to the CT02, use cables with a cross section
2
of 1.5 mm and with a maximum length of 25
m. The power supply device comes provided
with an output voltage regulated at 12.5-13
Vdc in order to compensate for any voltage

drops in the cables.
To connect the 12Vdc of the power supply device to
the CT02 see Fig. 4 and Fig. 5: use the appropriate
terminal blocks provided and suited for use with
cables with cross sections of 0.5-1.5 mm

3.3 General load connecting circuit

3.3.1 Connecting circuit of a 110-230V load
Fig. 4 shows a typical diagram of the connection of
a general electrically powered load.
Size the conductors according to the current
absorbed by the loads.
1) Connection of the power supply to the 110-230V line
2) Connection of the CT02 to the 12Vdc line
3) Connection of the 110-230V load
4) Connection of the start/pause button
provided
Fig. 4: Connecting circuit of a 110-230V load
The maximum current and switching voltage of the
relay is indicated in Chapter 1.3.
For these circuits use a double pole residual circuit
breaker with overload protection and with current
threshold of Idn=30 mA and current intervention (In)
sized according to that absorbed by the load.
The contacts can be used for closing low voltage
circuits or electrical signals.
