Installing the device

2, 3, 4: U0 phase (absorption)
Now the three-stage absorption charging process (U0 phase) begins, where the
duration depends on the battery. The voltage remains constant (U0). In the first
2 minutes, the charging of the battery is determined. Then the main charging phase
begins when the battery is fully charged.
Once the battery is completely charged, or the charging current is below 6 % of the
rated charging current for 15 minutes, the U0 phase has finished.
5: U phase (float)
After the U0 phase, the battery charger switches to conservation charging function
(U phase).
If DC loads are connected, they are powered by the device. Only if the power
required exceeds the capacity of the device is this surplus power provided by the
battery. The battery is then discharged until the device re-enters the I phase and
charges the battery.
6: 12-day conditioning
Every 12 days, the battery charger switches back to phase 1 for 85 min in order to
revive the battery. This prevents any fatigue symptoms such as sulphation.
7 Installing the device
When selecting the installation location, observe the following instructions:
• The device can be installed horizontally or vertically.
• Do not install the device
– In wet or damp environments
– In dusty environments
– In the vicinity of combustible materials
– In areas where there is a danger of explosions.
• The place of installation must be well ventilated. A ventilation system must be
available for installations in small, enclosed spaces. The clearance around the
device must be at least 25 cm.
• The air inlet on the underside and the air outlet on the back of the device must
remain clear.
• For ambient temperatures higher than 40 °C (such as in engine or heating
compartments, or direct sunlight), the heat from the device under load can lead
to reduced output.
