Electrical Connections - Ariston 801 Instructions For Installation, Use, Maintenance

ELECTRICAL CONNECTIONS

WARNING!
Before you get access to terminals, all supply circuits must be dis-
connected.
The appliance is supplied with a power supply cable (should the
latter need to be replaced, use only original spare parts supplied
by the manufacturer). It is advisable to carry out a check on the
electrical system to verify conformity to the regulations in force.
Verify that the electrical system can suitably withstand the water
heater's maximum power consumption values (refer to the data
plate), in terms of the size of the cables and their conformity to the
regulations in force. It is forbidden to use multiple outlet sockets,
extension cables or adapters. Ground connection is mandatory; it
is forbidden to use piping from the water, heating and gas systems
for earthing the appliance. Prior to operating the machine, make sure
that the electricity mains voltage conforms to the value indicated on
the appliance's data plate. The manufacturer of the appliance shall
not be held liable for any damage caused by failure to earth the sys-
tem or due to anomalies in the electric power supply. To disconnect
the appliance from the mains, use a bipolar switch complying with all
applicable CEI-EN regulations in force (minimum distance between
contacts 3 mm, switch preferably equipped with fuses).
The appliance must be connected in compliance with European and
national standards (NFC 15-100 for France), and must be protected by
a 30mA differential switch.
WARNING: the connection cables between the two units must not
be routed near junction boxes, wireless data transmission systems
(Wi-Fi routers) or other cables.
To make the electrical connections, see the wiring diagram.
Use all the plugs provided with the product as grommets or for plug-
ging the holes in the junction boxes.
PERMANENT ELECTRICAL CONNECTION (24h/24h)
Use this configuration whenever users do not have a two-tier elec-
tricity rate. The water heater will always be connected to the power
supply network to ensure 24h operation.

ELECTRICAL CONNECTION WITH DUAL POWER SUPPLY AND
HC-HP SIGNAL (power supply 24h/24h)
It offers the same cost advantages as the two-tier rate configuration
but, additionally, it provides rapid heating thanks to the BOOST mode
that activates the heating even with the HP rate.
1) Connect a bipolar cable to the appropriate signal contacts on the meter.
2) Connect the signal bipolar cable (C) to the appropriate EDF con-
3) Activate the HC-HP function through the P1 parameter in the
SECONDARY CONNECTION
If you have a PV system to be connected or an SG signal available,
you can connect a bipolar cable from the inverter or the SG signal
cable (alternatively, not both) to the connection box (secure the cable
into the dedicated cabling sheath).
Connect this cable (C) to the connector called "SG2" and activate the
PV (P11) or SG (P13) function via the installer menu.
WARNING: signal 230 V.
