Product description

The battery charger B71/BC/INT enables charging
two lead-acid batteries of 12Vdc, connected in
series, and in the absence of mains voltage supplies
energy to the power unit B70/1DC and B70/2DC,
activating the motors; it is provided the use of
batteries of 1200mAh (inserted into the battery
charger container) or batteries of 4500mAh (that
should be placed in a separate container, code BAT/
BOX, optional).
B71/BC/EXT is a kit that includes the battery charger
and the outer container complete with 2 batteries
of 4500mAh.
The battery should be chosen according to the

in the event you use the internal battery
(1200mAh): connect to terminal 5 (using the
wire jumper, figure 2)
if you use the external battery (4500mAh)
connect to the positive pole (see figure 3). The
internal batteries should be disconnected
4 in the event you use the internal battery
(1200mAh): do not connect
in the event you use the external battery
(4500mAh): connect it to the negative pole
(see figure 3). The internal batteries should be
disconnected

Use of internal batteries with B70/2DC
In case you use 2 internal batteries of 12Vdc
1200mAh refer to figure 2.
The battery charger should be installed – secured to
its compartment – inside the box of the power unit
B70/2DC; in this compartment are also inserted the
two batteries of 12V 1200mAh, connected in series,
6
and connected to the battery charger by means
of two red and black cable with standard Faston
terminals.
The terminal 3 should be connected to terminal 5 by
means of a jumper.
Disconnect the secondary circuit of the transformer
of the power unit B70/2DC, and connect it to
terminals 1 and 2 of the battery charger; connect
the output of battery charger (terminals 6 and 7) to
the power terminals of the power unit B70/2DC (see
figure 1).
Secure the container to the power unit box using
the self-locking screws supplied (figure 4, detail B).
WARNING! The external batteries should not be
connected.
4.2
Use of external batteries with B70/2DC
In case you use 2 external batteries of 12Vdc
4500mAh (B71/BC/EXT) see figure 3.
The battery charger should be installed – secured
to its compartment – inside the power unit box
B70/2DC; the batteries should be secured in the
container (code BAT/BOX) and connected to the
charging circuit by means of a cable with cross
section of 1.5mm for a maximum length of 3 metres.

Connect the cable that comes out from terminal 3
to the safety fuse installed in the container (figure
3, detail A): thus the positive pole of the battery is
connected in series with the fuse. Connect the cable
coming out from terminal 4 to the nearby position
(negative pole of the battery).
The two areas marked with "BR" should be
interconnected by means of small piece of tin.
WARNING! The internal batteries should be
disconnected.
