7 Technical description
The inverters can be operated wherever

a 12 V
g
connection (MSI912, MSI1312, MSI1812, MSI1812T)
 a 24 V
g
connection (MSI924, MSI1324, MSI1824, MSI1824T)
is available. The light-weight and compact construction of this device allows
for easy installation in mobile homes, commercial vehicles or motor and sail-
ing 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 indicated in chapter “Technical data” on page 58 . 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 ex-
ceeds 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 re-
start value.
 Excess temperature shutdown: The inverter switches off when the tem-
perature inside the device or the temperature on the cooling element ex-
ceeds 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 cir-
cuit 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.

Fuses (MSI 1812T and MSI 1824T only): The LED on the inverter indi-
cates an operating fault (constant red light). The fuse in the device must
be pressed in again by hand after it is triggered.
NOTE
Note when connecting devices with an electrical drive (such as
power drills and refrigerators), that they often require more power
than is indicated on the type plate.
