Rechargeable devices with USB interface can be charged via the USB port (5 V,
2000 mA).
This device is exclusively intended for vehicle use.
5 Technical description
The inverters can be used anywhere where there is a 12 Vg voltage source. The
inverters are connected to:
• Vehicle battery: MSI412 (12 Vg)
Devices MSI412 can be switched on and off optionally using an external switch.
The devices are additionally cooled with a load and temperature-dependent fan
(1).
The maximum constant output for the devices MSI412 is 350 W.
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 need more power
than is stated on the type plate.

If the system has a short circuit, the device switches off.
If the voltage is too high, the device switches off and must be restarted manually.
If the input voltage is too high or too low or the system overheats, the device
switches off and then on again after a short while.
The inverter has the following connections, displays and control elements:

6 Fastening the inverter
You can fasten the inverter using the four holders supplied.
When selecting the installation location, observe the following instructions:
•The inverter can be mounted horizontally or vertically.
•The inverter must be installed in a place that is protected from moisture.
•The inverter may not be installed in the presence of flammable materials.
•The inverter may not be installed in a dusty environment.
•The place of installation must be well-ventilated. A ventilation system must be
present for installations in small, closed spaces. The minimum clearance
around the inverter must be at least 25 cm.
•The air intake on the underside or the air outlet on the back side of the inverter
must remain clear.

MSI
EN 9
Connecting the inverter
•For ambient temperatures higher than 40 °C (such as in engine or heating
compartments, or direct sunlight), the heat from the inverter under load can
lead to the automatic shut-off of the inverter.
•The installation surface must be level and sufficiently strong.

➤Clip two holders on the lower left bar and two on the right.
You can move the holders as required.
➤Fasten the inverter by screwing one screw through each hole in the holders.
NOTICE!
Before drilling any holes, ensure that no electrical cables or other
parts of the vehicle can be damaged by drilling, sawing and filing.

7 Connecting the inverter
A
Make sure that a professional fuse is installed between the positive pole (+) and
the inverter. Mind the following values:
• MSI412: 40 A
Connecting the inverter
A
➤To set
up the
inverter, connect the red cable to the positive pole (+) of the vehicle battery
and the black cable to the negative pole (–) of the vehicle battery. Make sure
the vehicle battery terminals are clean when connecting them.
Connecting the external switch contact to the inverter
NOTICE!
The cable between the battery and the inverter may not exceed a
maximum length of 2 m.
NOTICE!
•If no sufficient, professional fuse is installed, the inverter could
be damaged and the gaurantee is invalidated.
•Do not reverse the polarity. Reversing the polarity of the
connections will cause a great spark and the internal fuses will
melt. These fuses should only be replaced by a qualified
electrician.
