The Protection Conductor Circuit (Pe) For Grounding - Favero 5197000015 Manual De Uso

Decide on the position of the TA1w
2.1.
Determine the position of the TA1w by paying attention to:
The regulations of the country in which it is to be installed with regards to the position of electric devices in
•
special areas (showers, swimming pools, etc.).
The important indications outlined in chapter 1.2, as to versions with different power supply voltages .
•
The path of the connection cables of the power supply device for the TA1w and for the solenoid valve. See
•
chapter 3 for information on connections .
2.2. Mounting to wall
Remove the protection case by unscrewing the three screws indicated in Fig 3 (Only for the TA1w version
•
100-240Vac).
Fasten the TA1w via the 4 holes at the bottom, as indicated in Fig 4. Make sure the device is fastened
•
vertically in order that it functions properly when coins are inserted.
Proceed with the electrical connections as indicated in chapter 3.

3. E
LECTRICAL CONNECTIONS
WARNING: It is absolutely mandatory that the installation of the product and the electrical system are designed and
implemented by qualified technicians, in compliance with regulations in effect in the country where installation takes place.
To access the connection terminals the protection case must be removed by unscrewing the 3 screws indicated in Fig 3
(Only for the TA1w version 100-240Vac).
The 3 separate 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 TA1w.
Connect the grounding conductor to the appropriate ring terminal provided, as indicated in Fig 5 for the TA1w version
100-240V, or in Fig 6 for the TA1w version 12Vdc. The terminal provided is suitable for cables with cross sections of
2
2.5–6 mm .
TA1w power supply circuit
3.2.
The TA1w needs a very low power supply, as indicated in chapter 1.3 The
2 versions are:
Power supply circuit for the TA1w version 100-240Vac
3.2.1.
The cables entering the TA1w through the appropriate grommets (Fig 4) must be double isolation cables.
Connect the power supply conductors to the terminals L and N of the power supply device, as indicated in Fig 5, using
the appropriate provided terminal forks suitable for cables with cross sections of 0.5 - 1.5 mm
To interrupt the supply of power to the TA1w use a 2A double pole residual circuit breaker with overload protection and
with threshold current (Idn) equal to 30 mA .
Power supply circuit for TA1w version 12Vdc
Place the provided power supply device inside an electrical panel far from the shower area, 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 7.
2) Use the appropriate terminal forks provided, which are suitable for use with cables with cross sections of 0.5 –
2
1.5 mm .
3) To connect the power supply device's 12Vdc to the TA1w, use cables with a cross section of 1.5 mm
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 TA1w see Fig 6: use the appropriate terminal blocks
provided and suited for use with cables with cross sections of 0.5-1.5 mm
