Attention!
The power inverter is equipped with a residual
current protection switch, which by residual cur-
rents >3mA at the safety contacts of the 220
- 240 V socket, switches the power inverter
off. If this should happen immediately remove
the device connected to the power inverter and
under no circumstances should you connect
this device to any other power supply! The
device is defective and must be examined and
if necessary repaired by a specialist before it
can be put back into service!
Device operation information
GENERAL NOTES
Usually on the device's rating plate you can find
information regarding the power consumption in
amperes (A) or the wattage (W).
Before operation make sure that the maximum power
consumption does not exceed 1,3 A and the maxi-
mum continuous load is not more than 300 W.
• Loads with a high internal resistance operate
very well with the power inverter, on the other
hand, loads with a low internal resistance, for
example heating and cooking devices have a
power consumption in watts that is too high.
• Inductive loads, for example, televisions or stereo
systems (devices with an inductor or a transformer)
often require a much greater switch on current
than resistance loads with the same specified
wattage. When switching on, television sets
demand much more power than that indicated
on the rating plate. Therefore it may be necessary
to switch the power inverter on and off several
times in order to switch the television set on.
• Most heat producing devices, for example, hair
dryers, clothes irons or heating fans can not be
operated via the power inverter because the
power consumption of these devices exceeds
the output power of the power inverter.
Low battery signal
• When the battery runs low (under 11 V) a conti-
nuous signal tone sounds to indicate that the bat-
tery needs to be charged. The operation
LED/Overload indicator continues to light up
green.
• When the battery voltage drops below 10 V the
power inverter switches off and the operation
LED/Overload indicator lights up red.
Changing the cable fuse
Risk of potentially fatal electrical
shock:
Disconnect the power inverter from the power
source before changing the fuse. Also remove
any devices connected to the power inverter.
The red cable with the connection terminal is equipped
with a fuse. When too great a load is connected to
the power inverter the fuse will blow.
Replace the fuse with one of the same value and
type as specified in the technical data and with the
same shut off characteristics.
Before switching on the power inverter again ascertain
and remedy the cause of the fuse blowing.
