The voltages depend on the number of
battery cells and the battery
manufacturer. They can be factory set
and are adjustable by the after-sales
support technicians.
An optional electronic board may be
used to continuously measure the
battery temperature and automatically
adjust the voltages.

Operation with Mains 1 down
(figure 12)
In the event of a Mains 1 failure or
Mains 1 voltage outside specified
tolerance of –10% in amplitude (–15%
optionally), the rectifier-charger stops
and the battery supplies the necessary
backup power to the load via the
inverter. The battery, float-connected
between the rectifier-charger and the
inverter, discharges during this
operating mode.
The green "load protected" light 5 on
the control panel is on.
The user is warned of battery operation
by a buzzer and the orange "load on
battery" light 4 on the control panel.

Note:
In the event of a Mains 1 failure,
frequency converters without a battery
shut down and the load is no longer
supplied.

The power necessary for the load is
provided by Mains 1 through the
rectifier-charger and the inverter.
The rectifier-charger also supplies the
power to float charge and recharge the
battery (1). The rectifier-charger output
voltage (DC) is regulated for the
different battery types and charging
modes:
