The inverter is switched off if the battery voltage drops below a factory-set minimum voltage value.

Never store the unit in this condition! The discharged battery system should be recharged within a week at the latest. When the voltage and frequency are within the tolerance range again after the mains is restored, the rectifiers switch back on automatically. The supply of the inverter through the mains is resumed and the battery charger charges the battery.

The bar graph LED (LED chain above the pictograph) indicates the remaining battery capacity during this operating mode (see chapter 8, p. 45).

Load

If the inverter is overloaded or if overtemperature is detected, e.g. also if an inverter defect is detected, voltage is supplied to the load without interruption via the static bypass switch (SBS) that switches on automatically. This is signalled by the Bypass LED.
