U
1
phase: Main charging with constant voltage
In the main charging phase, the voltage is kept at a constant value. As the bat-
tery increasingly charges, the current decreases continuously and approaches
a lower limit.

2
phase: Trickle charge with reduced voltage
In this phase, the charging voltage is reduced in order to maintain the battery
charge for an unlimited period and counteract self-discharge. Additionally
connected consumers are supplied via the charger in this phase without load-
ing the battery.

6 Setting charging characteristics
Notice
Battery defect due to incorrect charging
To protect the battery from damage due to incorrect charging, set
a suitable charging characteristic before installation. Follow the
battery manufacturer's instructions.
To set a charging characteristic, perform the following steps:
1. Turn the potentiometer to the desired position (see characteristics sheet in
Appendix).
