Electrical Connections - Riello BAG3 MIX BASIC Instructions For The Installaer And For Technical Assistance

INSTALLATION

2.6 Electrical connections

The BAG 3 is prearranged with rubber cable feed-throughs (1) located
in the top section of the box allowing wiring to be passed through.
Below is an explanation of how to correctly connect the BAG
the boiler and on devices.

Before carrying out any electrical intervention, set the main
system switch to "off".
Connecting the BAG 3 to the electrical power supply
− Pass the cable (2) which comes out of the electrical con-
nection box (3) through the cable feed-through (1) and
connect it to the electrical power supply (phase-neutral-
earth) making sure not to connect it below the boiler fuse.

Access to the BAG connection terminals

− To access the BAG connection terminals, loosen the four
screws (4) and remove the cover (3).

Connecting the BAG to the ambient thermostats/chrono-thermostats
− Carry out the connections of the ambient thermostats (TA)
and/or chrono-thermostats (CT) of each zone, as indicat-
ed in the diagram below. Before connection, eliminate
the relative jumper (TA1,TA2 or TAt3).

The ambient thermostats (TA) and/or chrono-thermostats
(CT) of the low and high temperature systems must be con-
4
nected directly to the BAG
section of 1 mm
9
The load represented by the pump will weigh directly on the
3
corresponding ambient thermostat (TA) and/or chrono-ther-
mostat (CT), therefore the TA and/or CT contact must be adapt-
ed to the application and be compatible with the electrical
rate of the pump not less than 6A (230Vac-50Hz).
Connecting the BAG
− Connect the CONNECT LE to the boiler (GEN) as indicated in
the diagram below.
9
Connect the mammut (B-B) of the BAG
of the boiler using a cable with a minimum section of 2x0.5
mm (please refer to the wiring diagram in the instruction
2
booklet for the installer of the specific boiler).
9
When using a phase-phase power supply, use a tester to
determine which of the two wires has the greater potential
compared to the earth and connect it to the L terminal. Con-
nect the remaining wire to the N terminal.
9
For floating power supplies, i.e. those which have no earth
connection, an insulation transformer must be used with a
secondary unit connected to the earth.
9
It is mandatory:
− to use a multi-pole trip-switch to disconnect the line in
compliance with CEI-EN standards (contact opening at
least 3 mm)
− to use cables with a 1.5 mm
(phase) - N (neutral) connection
− that the amperage on the switch is adequate for the boil-
