Technical description

7 Technical description
The inverters can be operated wherever
• a 12 Vg connection (MSI912, MSI1312, MSI1812, MSI1812T, MSI1812TOE)
• a 24 Vg 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 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 32. Never connect devices that have a
higher power requirement.

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.
The inverter has various protective mechanisms.
• Overvoltage protection: The inverter shuts itself off when the voltage exceeds
the cut-off value. It restarts when the voltage returns to the restart value.
• Low-voltage protection: The inverter shuts itself off when the voltage sinks
below the cut-off value. It restarts when the voltage rises to the restart value.
• High temperature protection: 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 temperature has reduced.
• Overload protection: 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 trig-
gered by excess current.
• Incorrect polarity protection: The incorrect polarity protection prevents the
wrong polarity when connecting the inverter.
• Device fuse (only MSI1812T, MSI1812TOE, MSI1824T): The LED on the
inverter indicates an operating fault (constant red light). The fuse in the device
must be pressed in again by hand after it is triggered.

The individual switching values are found in chapter "Technical data" on
