Electrical Connections
6.4 Cascade installation
6.4.1 Power supply
Each module (boiler) must be electrically pow-
ered. The connection must be made in accord-
ance with current regulations regarding elec-
trical safety, using a multi sheathed cable H05
VV-F-3GI with minimum section of the conduc-
tors of 1,5 mm
2
, properly protected against
humidity, abrasions and accidental contacts .
The electric connection has to be made for each
module as described in paragraph 6.2.1
6.4.2 Serial Connection
All the Pack of the battery must be connected
through a serial wiring which is already preset
on the different modules and contained inside
the board rack. The connection shall start from
the reference unit of the battery; unroll the ca-
ble, pass it through the opening made in the
back of the frame structure (after properly re-
moved the rubber stoppers present) and then
in the provided cableguides. Connect the cable
to the relative wiring of the successive Pack by
using the proper connector (see Figure 18).
The rubber cableguides placed on the
structure of the equipment have not to be re-
moved because their purpose is to protect the
cables from wear that occurs in direct contact
between cable and frame equipment. To pass a
cable is sufficient to drill the cableguides.
Once the connection has been made, all the
Pack of the battery will be as follows:

electrically powered;

connected to each other through a serial
wiring;

connected to the probes, to the pump and
to the reference pack.
In order to complete the electric installation,
select address for each slave as show in the
paragraph for “slaves boards settings” (see par
7.1).
