4.6 The Battery charger
4.6.1Cycle of charge
The full automatic COMPACT Battery Charger is adjusted at the factory so that most lead-acid and lead-gel batteries can be charged to the maximum. As soon as the minimum alternating voltage for the AC IN set on the Turning Knob 23 is available at the input (LED 1 AC IN is lit), the Battery Charger is switched on automatically (LED 2 CHARGER is lit). The battery is fully automatically charged matching to the charge level, the adjusted voltage levels and the charge current. Thanks to the built-in Float Charge System, the batteries can be left connected for unlimited time with the Battery Charger switched on.
During the charging phase the consuming devices at the outlet AC OUT are continually supplied with power (LED 8 AC OUT is lit).
The charger functions are shown in the following diagram:

4.6.2Equalization charging
Before you program the COMPACT for Equalization-charge you must confirm with your supplier that the batteries are suitable for this process.
Equalization is recommended for the lead-acid batteries in order to mix well the electrolyte fluid and to clean the lead plates.
Equalization mode should never be used when using Gel-Batteries
If the COMPACT is operating with a lead-acid battery, which is suitable for equalization, the slide switch „Equalize“ which is on the cable connection side, must be placed in the ON position. In this setting, at every 25 charge cycles an equalization is carried out for 20 min. (factory setting). During such a charge cycle the LED 14 is lit. Charge cycle with equalization can be started independently of the actual program. For this the slide switch must be slid from “OFF” to the “ON” position. The LED 14 will light up. If the periodic equalization is not required, slide switch must be slid back to the „OFF“ position after the completion of the manual cycle.
CAUTION: During the equalization process, the batteries produce lot more gas.
DANGER OF AN EXPLOSION !!
4.6.3Input current repartition (Power sharing)
For manage the power available on the AC INPUT (depend the supply use) the COMPACT is equipped with a system usually called “Power sharing” or INPUT power distribution. With this function it’s possible to limit the AC INPUT current assigned to the charger. More current it uses on
