• Insert the 12 V vehicle plug into a vehicle recep-
tacle.
Note:
Due to high crossover resistances heating of
the plug in connector can result when using the
cables with a 12 V vehicle plug. Therefore
when operating with high loads use the con-
nection cable with the connection terminals.

Connection to an automobile battery

• Loosen the red screw on the power inverter as
much as is needed for you to be able to place
the red cable shoe of the red cable with the
connection terminal with the opening under the
screw and washer.
• Turn the red screw so tight that the cable shoe
can no longer become unattached.
• Loosen the black screw on the power inverter as
much as is needed for you to be able to place
the black cable shoe of the black cable with the
connection terminal with the opening under the
screw and washer.
• Turn the black screw so tight that the cable shoe
can no longer become unattached.
• First connect the red terminal clamp to the plus
pole of the automobile battery and then the
black terminal clamp to the minus pole of the
battery.
Attention!
Do not use the power inverter in vehicles who-
se plus pole is connected to the vehicle body
and/or the chassis.
The positive pole must be inside the receptacle.
Do not use the power inverter in vehicles with
positive earth receptacl es. Otherwise the de-
vice will be damaged.
Connection and operation of aload/device
Attention!
Before connecting a load/device to the power in-
vertermake sure that the on/off switch on the
device is in the position 0.
Make sure that the power of the load/device
does not exceed the maximum continuous load of
the powerinve rter.
• Insert the plug of the connecting load/the device
to be operated into the 220 - 240 V socket of
the power inverter.
Attention!
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/Over-
load indicator will light up green.
• 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/Ove rload indicator lights up red the input
voltage is too low or the power of the load/de-
vice connected to the power inverter is too
high.
