CHARGING PROGRAMS
Choose program by pressing the MODE-button.
Adjust parameters according to "CHARGING" (6–8).
Press START/PAUSE button to start the selected program.
The table explains the different Charging Programs:
Program Battery Size
(Ah) Explanation Temp range
NORMAL 40–150 0A h
20–750Ah Use for WET and MF batteries. -20°C–+50°C
(-4ºF–+122ºF)
Ca/Ca 40–1500A h
20–750Ah
Use for Ca/Ca batteries. Use Ca/Ca-program to maximize charge with
minimum loss of fluid. Including RECOND step. Recond your battery once
per year and after deep discharge to maximise lifetime and capacity.
-20°C–+50°C
(-4ºF–+122ºF)
AGM/GEL 40–1500Ah
20–750Ah For AGM and GEL batteries which are recommended to receive lower voltage charge. -20°C–+50°C
(-4ºF–+122ºF)
AGM POWER 40–1500A h
20–750Ah Use for AGM batteries which are recommended to receive higher voltage
charge. -20°C–+50°C
(-4ºF–+122ºF)

charger
2. Connect the mains cable to the charger
3. Connect the red clamp to the battery´s positive pole.
4. Connect the black clamp to the vehicle chassis remote from the fuel pipe
and the battery.
5. Connect the charger to the wall socket
6. Disconnect the charger from the wall socket before disconnecting the
battery
7. Disconnect the black clamp before the red clamp
WARNING!
Risk for short circuiting the battery cables. Connect charger cables
to the charger before connecting the battery
WARNING!
Risk for electrical shock if touching positive and negative terminals
when charging

• Using higher current than recommended may result in batteries not being
completely charged.
•Using lower current than recommended will prolong the charging time.
• The currents are the maximum recommended current for battery charg-
ing. If a parallel consumer is connected then the current setting could be
increased with this current value.
• Some battery manufacturer could recommend different values. Please
check with the manufacturer if uncertain. The main recommendations are
that Gel batteries should be charged in the lower current range, Power
AGM’s in the upper range and most other battery types in the mid-range.
*) 70/35A Could only be selected for Supply program
Some vehicles may
have positively
earthed batteries
3. Connect the black
clamp to the battery´s
negative pole.
4. Connect the red clamp
to the vehicle chassis
remote from the fuel
pipe and the battery.
7. Disconnect the red
clamp before the black
clamp.

MOUNTING
When permanently mounting the charger, mount the charger on a firm
surface. Fix the charger with screws in the four holes. Use screws intended for
the surface. Allow space around the charger to not interfere with air cooling.
CHARGING PROGRAMS
*) SUPPLY program is not time or voltage limited
STEP 1 DESULPHATION
Detects sulphated batteries. Pulsing current and voltage, removes sulfates from
the lead plates of the battery restoring the battery capacity.
STEP 2 SOFT START
Tests if the battery can accept charge. This step prevents charging a defect
battery.
STEP 3 BULK
Charging with maximum current until approximately 80% battery capacity.
STEP 4 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
STEP 5 ANALYSE
Tests if the battery can hold charge. Batteries that can not hold charge may
need to be replaced.
STEP 6 RECOND
Choose the Ca/Ca program to add the Recond step to the charging process.
During the Recond step voltage increases to create controlled gasing in the
battery. Gasing mixes the battery acid and gives back energy to the battery.
STEP 7 FLOAT
Maintaining the battery voltage at maximum level by providing a constant
voltage charge.
STEP 8 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery
voltage and gives a pulse when necessary to keep the battery fully charged.
