Operation Manual

INTRODUCTION
This manual contains important operating and safety instructions, before starting to
use the battery charger it is important to read and understand the safety instructions in
this manual.
Safety notes
–Before each use please check the battery charger, the connection cable and the
connector. If any malfunction is detected do not use it! It is strictly forbidden to
open the device. Repairs may only be carried out by qualified technicians using
original spare parts. A charger, a cable and or a damaged connector increases
the risk of fatal electric shocks.
–Do not place the charger on highly flammable surfaces or environments (ex .:
paper, cloth etc ...). The overheating of the device during the charging phases
can increase the risk of fire.
–During operation the device should be placed in a well-ventilated place.
–If the power supply cable is damaged it must be replaced by a qualified
technician to eliminate the risk of accidents.
WARNING
– Never charge a cold or non-rechargeable battery!
– Keep the device out of the reach of children
– The device must be protected from sunlight or direct heat sources to prevent
overheating.
– To reduce the risk of malfunctions do not block the ventilation bores.
– DO NOT install the unit in a sealed environment, otherwise it may overheat.
– To avoid the risk of electric shock and or fire, make sure that the power
supply system is in good condition.
– DO NOT use the charger with damaged cables and or with inadequate
section.
– DO NOT use the battery charger in an environment with high humidity or in
direct contact with splashes of water and or other liquid or in the rain.

Before installing and using the charger, please set the most suitable charging curve
for the type of battery to be charged. The charger is equipped with
DIP-SWITCHES to select various charging curves, as shown in the following table:
DP1 DP2 PHASES DESCRIPTION
OFF OFF IUIa AGM For AGM batteries
OFF ON IUIa Acd For Lead Acid Flooded traction batteries
ON OFF IUUa Generic curve for GEL and AGM batteries
(Default setting)
ON ON IU LiFePO4 For LiFePO4 lithium battery
ON ON IUIa - GEL For GEL batteries and all Lead Acid Flooded
(Only for model 12V - 10A)
The DIP-SWITCHES are behind a black plastic cover on the front panel of the
device, so in one of the two shorter sides.
In some models, there are 4 DIP-SWITCHES but only the two switches on the left
are used
FUNCTIONING
After setting the DIP-SWITCHES of the charger, by connecting it to the battery and
to the mains, the device signals the operating status with LEDs of different colors.
According to the model there are 3 or 5 LED indicators, as shown in the
following pictures:
The LEDs on the charger have the following meanings:

Some devices have two pairs of output cables that may also have the same color but
of different section: The pair of cables of larger section is the power output of the
charger, which must be connected to the battery, while the other pair
consists of a dry contact of a NORMALLY OPEN relay. Connecting one cable to
the battery voltage, the Normally Open contact, can be used to turn on a 12V lamp
(or LED) when the main line is connected.
If the pair of cables with the larger section is BROWN BLUE color, the
POSITIVE is the BROWN cable.
The cooling fan fans are electronically controlled by the microcontroller which
decides the power and speed according to the conditions of the internal and
environment temperatures.
