5� Connect the black battery cable (10) with the eyelet to the negative pole of
the battery�
This is black or marked with „N" or „-".
Without an earth connection, there is a risk of electric shock in the event of equip-
ment failure.
6� Connect the grounding cable (11) to the ground terminal (3) and to an avai-
lable grounding system (e�g� the vehicle body; or to the potential output in
case of stationary use)�

Operation
6.1 In general
Some external devices such as audio and battery-powered devices and precision
equipment may not be suitable to operate at a voltage converter and the connec-
ted device and/or the voltage converter may get damaged�
1� Check the user manual of the device to be connected to corresponding no-
tices�
2� Turn the device off immediately and unplug the power cord when it hums
or excessively heates up�
3� If there is anything unclear, contact the dealer of your device�
Both AC outputs 230 V (7) and the DC output USB 5 V (8) can be used simulta-
neously� The total power rating for all connected equipment must not exceed the
continuous output of the voltage converter� The power rating of your equipment
can be found on the nameplate� External devices, such as electric motors, drills,
electric saws, refrigerators and music systems normally have a higher rated pow-
er when starting as indicated on the nameplate�
The voltage converter can therefore briefly make a higher peak output power if
the power rating is only given in current as ampere,
•
multiply the value in amperes (A) by a factor of 230 to to obtain the pow-
er in watts (W)�
Example: 0�5 A x 230 V = 115 W
The vehicle battery discharges when the vehicle is not in operation.
6.2 Switching the voltage converter on/off
1� Turn the On/Off switch (9) on (ON).
If the Operation LED (5) lights up, the voltage converter is ready for ope-
ration.
2� If the the Error LED (6) lights up, turn off the voltage converter by pressing
the On/Off switch (OFF).
