Error tracing
Separate the voltage converter from the
12V- power supply and the external devices
from the outputs in one of the cases listed.
= Error
= Possible cause
= Remedy
No LED-display lights up.
The pole terminals
6
and
7
are not con-
nected correctly with the power supply.
Examine all connections.
No input voltage.
Examine all connections.
LED-display

lights up red.
The temperature is above 68 °C.
Switch of the voltage inverter immediately.
Examine if the voltage converter is suffi-
ciently cooled and the cooling grids and the
cooling fan
13
are free.
Let the device cool down and provide suffi-
cient ventilation.
Wait for 10 minutes before you switch on
the voltage converter again.
The input voltage is too high; over-voltage
protection.
Switch of the voltage inverter immediately.
Examine the input voltage.
The input voltage is too low; Under-voltage
protection.
Switch of the voltage converter immediately.
Examine the connection and charge the
battery.
If the voltage is above 12 V, restart the
voltage inverter.
Wrong connection of the poles; Short circuit
protection.
Switch of the voltage converter immediately.
Examine all connections, cables and appliances.
Connect the connections correctly.
The nominal capacity was exceeded (see
technical data); Current-overload protection.
Use appliances which do not exceed the nomi-
nal capacity according to the “technical data”.
Short circuit in the device.
Examine the connected appliances. Do not
use the concerned appliances.
= Error
= Remedy
In TV-operation and / or sound systems
and / or devices:
Snow picture, wobbly picture, hum, knock
or buzzing.
Place the voltage converter as far as possible
from the TV.
Examine the antenna connection und setting.
Move the antenna cable further from the
voltage inverter. Use a shielded antenna
cable. The modified sin wave of the voltage
converter could be filtered not sufficiently
by the connected external device. Separate
all cables immediately.
The only available solution is the use of a
modern external device respectively a device
with a higher capacity and sufficient filtering
capacity.
Maintenance and care
The device is maintenance-free.
WARNING!
Always separate electrical
devices from the power supply, before you carry
out service etc.
Switch off the device. Keep the key ON/OFF/
MODE
3
pressed for approximately 3 seconds.
Remove the terminal clips

from the
battery as described above.
