Operation / Error tracing
Switch on / off the voltage
converter, change mode
Press and hold the ON/OFF/MODE key
1
for
3 seconds to power on the voltage convert-
er. The converter will now automatically per-
form a self-test. During this process all LEDs,
the fan and the alarm buzzer will activate
briefly for approx. 2 seconds.
Once the self-test has been completed the
converter is ready for use and the green LED
5
will light up. The LED display
2
will also
show the output being drawn, in watts. Pro-
vided no loads are connected to the 230 Volt
output socket
9
the LED display
2
will
show 0 – watts.
Press and hold the ON/OFF/MODE key
1
for
3 seconds again to power off the voltage
converter. The converter will power off and
the displays will turn off.
When pressing the ON/OFF/MODE key
1
briefly (1 second) with the converter on the
LED display
2
will switch between watts
and volts.
Replacing fuses in the fuse holder:
Disconnect the voltage converter from the
power supply by unplugging the 12V plug
3
from the 12V on-board outlet. If neces-
sary, also unplug any connected loads from
the 230V output socket
9
and the USB
output
8
.
Loosen the retaining screw on the fuse hold-
er using a cross slot screwdriver, turning it
counter clockwise. Now carefully open the
cover on the fuse holder, pulling the cover
up.
Remove the defective fuse and replace it
with a new fuse with the same ampere rat-
ing. (max. 20A fuse). Be sure the fuse is se-
curely seated in the fuse holder, use of a
fuse puller is recommended.
Now close the cover of the fuse holder and
tighten the cross head screw on the cover.
Now reconnect the converter to the on-
board outlet without any loads connected
and power on as described.

Examine all connections.
No input voltage; the 12 V-connection has
no voltage.
Switch on the starter.
Faulty fuse
Replace the fuse.
LED-display

lights up red.
The temperature is above 65 °C.
Switch of the voltage converter immediately.
Examine if the voltage converter is sufficiently
cooled and the cooling grids
7
are free.
Let the device cool down and provide sufficient
ventilation.
Wait for 10 minutes before you switch on
the voltage converter again.
The input voltage is too high; Overvoltage
protection.
Switch of the voltage converter 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 devices.
