6 Intended use
!
The wave inverter converts direct voltage of 24 Vginto a 220 V AC supply of 50 Hz
or 60 Hz.
7 Technical description
The inverters can be operated wherever a 24 Vgconnection is available. The light-
weight and compact construction of this device allows for easy installation in mobile
homes, commercial vehicles or motor and sailing yachts.
The output voltage corresponds to the household voltage from the socket (pure sine
wave, THD < 3 %).
Please observe the values for constant output power and peak output power as indi-
cated in chapter “Technical data” on page 22. Never connect devices that have a
higher power requirement.
I
The inverter has various protective mechanisms.
•Overvoltage shutdown: The inverter shuts itself off when the voltage exceeds
the cut-off value. It restarts when the voltage returns to the restart value.
•Undervoltage shutdown: The inverter shuts itself off when the voltage sinks
below the cut-off value. It restarts when the voltage rises to the restart value.
•Excess temperature shutdown: The inverter switches off when the tempera-
ture inside the device or the temperature on the cooling element exceeds a cut-
off value. It restarts when the voltage rises to the restart value.
•Overload shutdown: The LED on the inverter indicates an operating fault
(constant red light) when an excess load is connected or a short circuit has
occurred. The fuse in the device must be pressed in again by hand after it is
triggered by excess current.
•Incorrect polarity protection: The incorrect polarity protection prevents the
wrong polarity when connecting the inverter.
WARNING!
Never use the inverter on vehicles where the positive terminal of the bat-
tery is connected to the chassis.
NOTE
Note when connecting devices with an electrical drive (such as power
drills and refrigerators), that they often require more power than is indi-
cated on the type plate.
