ELECTRICITY MAINS
BAG 2 MIX CLIMA unit to the electricity mains (phase /
neutral / earth) using the cable supplied.
Drawing the power supply for the BAG
MA from theboiler is absolutely forbidden as the
boiler's fuse is not sizedto take the electrical loads
associated with the BAG
CONNECTING THE AMBIENT THERMOSTATS (TA)
The TAs for the low (TA2+) and high (TA1+) temperatu-
re system must be directly connected to the BAG
MIX CLIMA (fig. 2) using a cable with minimum section
1 mm 2 .
BAG 2 MIX CLIMA CONNECTION TO THE BOILER

to the N terminal.
For floating power supplies, that is, those that have
no earth connection, an insulation transformer must
