Electrical connections

The device is supplied already wired for the mains
power supply. It is powered through a flexible
cable and a socket/plug combination (Fig. 8 and
Fig. 9). An earthed Schuko socket with separate
Fig. 10 – Example of a remote link
protection is needed for the connection to the
mains power supply.
WARNING! The power supply to which the
equipment will be connected must be
protected by an adequate residual current
circuit breaker.
The type of residual current circuit breaker
must be chosen by evaluating the type of
electric equipment to be used on the entire
system.
With reference to the connection to the
mains power supply and the safety
equipment (e.g. residual current circuit
breaker) comply with standard IEC 60364-
4-41.

Remote links

The equipment is designed to be connected to
other remote energy systems (photovoltaic and
solar thermal power systems).
The user interface has two digital inputs with the
following functions:
Digital 1:
Input
The "Green" function is enabled when a free
contact is established between terminals 31 and
32
(cable: white/green).
overproduction of electricity and it increases the
temperature of the water in the storage tank until
it reaches the temperature set by the user (70°C
default temperature);
Digital 2: Input from photovoltaic system.
The "Green" function is enabled when a free
contact is established between terminals 31
and 32 (cable: white/green). This function
exploits any overproduction of electricity and
it increases the temperature of the water in the
storage tank until it reaches the temperature
set by the user (70°C default temperature).
4.2.1.1 Remote link mode
As regards links to digital inputs, the equipment is
provided with an additional 4-core cable that has
already been linked to circuit board of the user
interface (placed inside the equipment Fig. 12).
The remote links to any energy systems must be
carried out by a qualified installer (junction boxes,
terminals and connection cables).
The following illustrations show an example of a
remote link (Fig. 10 e Fig. 11).
