- Power inverter with 12 V vehicle plug
- This operating manual
Operational information
For continuous operation of devices via the power
inverter the 12 V vehicle socket must supply a voltage
between 11 - 15,5 V .
The voltage source of the 12 V vehicle socket can
be perhaps an automotive battery or a regulated
DC voltage like a transformer-accumulator station.
Before connecting the power inverter check to see
that the voltage source is supplying sufficient power
for operation.
The required power needed for operation can be
calculated as follows:
Example
The power source should also supply at least 14,7 A.
Attention!
Never connect the power inverter to a 24 V
supply system. Otherwise the device will be damaged. The device can only be connected to a
voltage source with a nominal voltage of 12 V.
Setup
• The power inverter should be positioned on an
even, flat surface. Make sure that there is 1 cm
free space remaining all around the power inverter
for air circulation.
• A distance of 50 cm must be maintained behind
the fan's ventilation slots.
In vehicle operation
If you are operating the power inverter in a vehicle
make sure that the installation is not a hindrance
when driving the vehicle. For this, install cables so
that they do not come into contact with moveable
parts in the vehicles interior and they do not obstruct
the view.
Note:
The power inverter can also be operated when
the engine is switched off. However be aware
that the power inverter possibly may not function during an engine startup.

Connection to a voltage source
Attention!
Before connecting the power inverter to a voltage source make sure that the on/off switch on
the device is in the position 0.
• Insert the 12 V vehicle plug into a 12 V vehicle
receptacle.
Attention!
Do not use the power inverter in vehicles whose plus pole is connected to the vehicle body
and/or the chassis.
The positive pole must be inside the 12 V receptacle. Do not use the power inverter in vehicles
with positive earth 12 V receptacles. Otherwise
the device will be damaged.
Connection and operation
of a load/device
• Now switch on the load/device to be operated.
When switched on a short signal tone can be
heard.
Note:
If a signal tone can be heard and the operation LED/Overload indicator lights up red the input voltage is too low or the power of the
load/device connected to the power inverter is
too high.
Attention!
The power inverter is equipped with a residual
current protection switch, which by residual currents >3mA at the safety contacts of the 220 240 V socket, switches the power inverter off.
If this should happen immediately remove the
device connected to the power inverter and under
no circumstances should you connect this device
to any other power supply! The device is defective and must be examined and if necessary
repaired by a specialist before it can be put
back into service!
Attention!
Before connecting a load/device to the power inverter make sure that the on/off switch on the
device is in the position 0.
Make sure that the power of the load/device
to be run that you intend to connect to the power inverter does not exceed the continuous load
rating specified in the power inverter's technical
data.
• Insert the plug of the connecting load/the device
to be operated into the 220 - 240 V socket of
the power inverter. Do not switch on the load/
device to be operated yet!
• Switch the power inverter on by moving the on/off
switch to the position I. If the power inverter is
functioning properly the operation LED/Overload
indicator will light up green.
Device operation information
General notes
Usually on the device's rating plate you can find
information regarding the power consumption in
amperes (A) or the wattage (W).
Before operation make sure that the maximum power
consumption does not exceed 0,65 A and the maximum continuous load is not more than 150 W.
• Loads with a high internal resistance operate
very well with the power inverter, on the other
hand, loads with a low internal resistance, for
example heating and cooking devices have a
power consumption in watts that is too high.
- 5 -
• Inductive loads, for example, televisions or stereo
systems (devices with an inductor or a transformer)
often require a much greater switch on current
than resistance loads with the same specified
wattage. When switching on, television sets demand
much more power than that indicated on the
rating plate.
Therefore it may be necessary to switch the power
inverter on and off several times in order to switch
the television set on.
• Most heat producing devices, for example, hair
dryers, clothes irons or heating fans can not be
operated via the power inverter because the
power consumption of these devices exceeds
the output power of the power inverter.
• In the event of uncertainty, please consult the
manufacturer of the connected appliance.
Low battery signal
• When the battery runs low (under 11 V) a continuous signal tone sounds to indicate that the battery needs to be charged. The operation
LED/Overload indicator continues to light up
green.
• When the battery voltage drops below 10 V
the power inverter switches off and the operation
LED/Overload indicator lights up red.
Television sets
• The power inverter is shielded and puts out a filtered sine wave. With the reception of, for example,
very weak television stations it can, nevertheless,
result in interferences and/or image breakdown.
• In this case position the power inverter as far
away as possible from the television, antenna
cable and antenna.
• Reposition the power inverter, television, antenna
cable and antenna until reception improves.
• If possible use a high quality, shielded antenna
cable.
Audio systems
• Some audio/video systems issue a buzzing tone
through the speaker when they are being operated
via the power inverter. The reason for this is that
these devices can not filter the modified sine
wave of the power inverter and this is not a defect
in the power inverter.
Handling general failures
Electrical tools
• When an electrical tool will not switch on or
only runs for a short time switch the power inverter
on and off several times while the electrical tool
is switched on.
