6.8 ELECTRICAL CONNECTIONS
The device is equipped with a power cable with Schuko plug
to be connected to the power grid via a suitable socket (fig. 38
and fig. 39).

ATTENTION
The device must be installed in
compliance with the regulations
on electrical systems in force in
the country of installation.
OBLIGATION
Connect the device to an efficient
grounding system.
PROHIBITION
Do not use extension cords or
adapters.
ATTENTION
For connection to mains and
safety devices, comply with the
IEC 60364-4-41 standard.
ATTENTION
Fixed devices are not equipped
with means of disconnection
from the mains with a separation
of the contacts on all poles ca-
pable of guaranteeing complete
disconnection in the
overvolt-
age category III
, the instruc-
tions indicate that the means of
disconnection must be integrat-
ed in the fixed wiring in compli-
ance with the wiring regulations.
ATTENTION
The device must be protected by
an adequate differential switch.
The type of differential switch
should be selected by assess-
ing the type of electrical devices
used by the system as a whole.
ATTENTION
DO NOT TAMPER WITH THE
POWER CORD.
If the power supply cable is dam-
aged, it must be replaced by the
manufacturer or the technical as-
sistance service or in any case
by a person with similar qualifi-
cations, in order to prevent any
risk.
6.8.1 Remote connections
The equipment is prearranged to be connected to other remote
energy systems or energy meters (solar thermal, photovoltaic,
Off-Peak)
INPUTS
• Digital 1
(DIG1)
. NOT USABLE.
• (THE TWO WIRES, WHITE AND BROWN, OF THE 6-CORE
CABLE ARE NOT TO BE USED).
• Digital 2
(DIG2)
. Digital input for photovoltaic. In case of a
photovoltaic system connected to the plant, it can be used
to subtract energy in the form of hot water in times of over-
production. If there is a voltage-free contact, e.g. from the
inverter, which closes when there is overproduction of ener-
gy, it can be connected to the two
green
and
yellow
wires of
the 6-core cable supplied with the device. Set the parameter
P23 = 1
to activate the supplement with photovoltaic.
