9. POWER SUPPLY
Short-circuit protection - If the wires are crossed or the
output has short-circuited, this usually causes the 20 amp
fuse to blow. Unplug the load from the power inverter and
exchange the fuse.
Overheating protection - If the internal temperature of
65℃ is exceeded, the unit switches off automatically.
After a cool-down phase of approx.15 minutes, the unit
can be switched on again.
9.9. General Problems
Some inductive motors may require several start-up
attempts. If the device only runs for a moment, switch the
power inverter on and off quickly and repeat until the
device runs.
Humming in music systems
The loudspeakers of some stereo systems may hum as
they cannot filter the modified sine waves that the power
inverter generates.
Problems when operating a TV
The power inverter is already screened, although there
may be visible interference, especially if the TV signal is
weak. Try one of the following actions:
Position the power inverter as far away as possible from
the unit, the aerial and the aerial cable.
Look for the best possible position for the aerial cable, the
power cable, the TV and the power inverter, use good
quality aerial cables.
