BATTERY INSTALLATION

To insert batteries in the battery compartment
(Photo F - 2) it is necessary to lower the brush
plate to the floor.
To access to the battery compartment, pull the
opening lever (Photo L - 1) and lift the recovery
tank (Photo I - 3).
Detach the spring clip (Photo F - 1) placed on the
lifting cable of the brush plate.
Place the batteries in the battery compartment
(Photo F - 2) checking that they are in perfect con-
ditions.

BATTERY CONNECTION

• These operations must be carried out by specia-
lized personnel.
Install and charge the batteries in a dry ventila-
ted place, far from sources of heat and corrosive
substances. Make sure that the voltage between
the batteries and the battery charger corresponds.
Protect the circuit with a delay switch or a fuse with
a higher charge than the maximum absorption of
the battery charger. Comply with the polarity of the
battery plug.
Disconnect the Anderson connector of the battery
wiring from the Anderson connector of the machine
wiring (Photo D - 1). Always hold the connectors
with the hands and never pull on the cables.
Photo G show connection diagram of the batteries
for KF455BBC (DC 24V) machines.
• Attach the battery wiring to the battery,
connecting the terminals only on the poles
marked with the same symbol (red wiring
"+", black wiring "-")!
A battery short-circuit may cause an explo-
sion!
After checking that all the controls on the panel
are in position "0" or at rest, connect the battery
connector to the machine connector.
( ! ) Close the battery compartment making sure
not to crush any wires.
Photo F - 3 show the correct connection of the
batteries for KF455BBC (DC 24V) machines.
5.2 BATTERY CHARGER CONFIGURA-
TION
• We recommend to call the assistance centre or
a technician if you have problems with the setting
given.
The machine is equipped with a battery charger
configurated for GEL batteries
If the operator whish to use Pb-Acid battery, it is
necessary change the battery charger settings as
follows:
• DISPLAY OF THE BATTERY CHARGER SETTINGS
The battery charger settings are shown by the blin-
king of the LED indicator when the battery charger
is switching on:
- the RED LED indicator ( Photo E - 2 ) flashes
2 times = the battery charger is set for PB-Acid
batteries
- the GREEN LED indicator ( Photo E - 3 ) flashes 2
times = the battery charger is set for GEL batteries
The battery charger settings will be displayed even
if batteries are not connected.
• DIP-SWITCH CONFIGURATION FOR BAT-
TERY CHARGING CURVE
To set the charging curve type for Pb-Acid, GEL
or OPTIMA batteries it is necessary to operate on
the dip-switches placed inside the battery charger
( Photo E -4 ).
The dip-switches available for the setting of the
charging curve are on the control card ( Photo E
- 4 ) that is placed behind the lower panel of the
battery charger ( Photo E - 1 ). It is also possible
to reach the dip-switches by removing the plastic
cap ( Photo E - 5 ).
For the setting of the charging curve for each kind
of batteries it is necessary to place the dip-switches
SW1 ( Photo E - 6 ) as shown in the following table:
Battery type
Optima
Pb-Acid
Gel / AGM
NOTE: the position of all the remaining dip-
switches must NOT be changed.
