2: Reconditioning
With a voltage between 10.5 V and 12 V, an approx. 2 A current will be delivered (timeout 8 h).
3: Bulk charge
House battery (B1): With a voltage between 12 V and V
constant current will be delivered depending on the model:
• SCE320, SCE320B: 20 A
• SCE360, SCE360B: 25 A
Starting battery (B2): With battery voltage between 12 V and 14.4 V, a constant current of a 5 A will be delivered .
4: Absorption charge
House battery (B1): With battery voltage equal to V
stant voltage equal V
state of charge (SoC) increases to approx. 3 A (timeout 6 h).
Starting battery (B2): With a battery voltage of 14.4 V a constant voltage of 14.4 V will be delivered. The delivered
current will decrease when the battery state of charge (SoC) increases to approx. 3 A (timeout 6 h).
5: Desulfation (only house battery, only if selected)
An approximately 2 A constant current will be delivered, allowing the battery voltage to rise to the maximum value of
15.8 V. This phase ends after reaching of 15.8 V (timeout 2 h).
6: Maintenance
House battery (B1): The maintenance phase keeps a constant voltage related to the selected charging curve
(V ). This phase has a timeout of 4 h for the LiFePO4 charging curve with maintenance ON, while for the other
maint
curves there is no time limit. If during the maintenance phase the voltage drops below values of 13.5 V for the LiFe-
PO4 curve, 12.65 V for the Wet curve, and 12.8 V and for the other curves, charging will be restarted beginning at
the first phase (timeout 4 h).
Starting battery (B2): The maintenance phase keeps a constant voltage of 13.5 V (timeout 8 h).

8 Installation

Before installation
Observe the following instructions when selecting an installation location:
• Ensure that the mounting surface is solid and level.
• Choose an well ventilated installation location to avoid overheating.
• Observe a distance of 10 cm to the ventilation openings of the cooling fan.
Choose a suitable installation location to connect the power cables to the battery.
