Note
The output voltage can only be measured correctly with a True-
RMS measuring device.
Fault Cause Remedy
No output voltage No contact to the battery Check contact and cable.
Switch on the ignition if
necessary.
Overheating Switch off the consumer.
Let the inverter cool down
and ensure better ventilation.
If necessary, reduce the
constant load.
Input voltage too high Check the input voltage on
the inverter and compare with
the technical data for the
inverter.
Defective fuse (in the inverter
or the vehicle)
Replace the fuse with one of
the same specifications.
Defective device Replace the device.
The device switches on and
off repeatedly
Excessive constant load Reduce the load.
The inverter switches off
when the consumers are
switched on
Starting current too high Compare consumer power
with the maximum power
from the inverter.
The output voltage is too low Battery voltage is lower than
shutdown value (see “Low
voltage shutdown” in chapter
“Technical data” on page 41)
Charge the battery (start the
engine).
