5.5 Solar power system integration

The following illustration (Fig. 10) shows an example of
solar power system integration.

5.6 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. 11 and Fig. 12).An earthed
Schuko socket with separate protection is needed for the
connection to the mains power supply.

5.6.1. 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 2: Input from photovoltaic system.
"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 1: Input from the solar thermal power system.
The heat pump operation is disabled for a set time
when a free contact is established between terminals
30 and 31 (cable: brown/yellow) The cycle has the
purpose of optimizing the performance of the solar
thermal power system.

WARNING! The power supply to
which the equipment will be
connected must be protected by
an adequate residual
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
residual current circuit breaker)
comply with standard IEC 60364-
4-41.
