PROBLEM POSSIBLE CAUSE SOLUTION
The connected
device does
not switch on.
The battery is defective. Check the battery and replace it if required.
The power inverter is
damaged and needs to be
repaired.
Have the power inverter repaired by an
authorized service centre.
Connection to the power inverter
or 12 V outlet is not tight. Check all connections. Make sure the
connection is correct and tight.
Measured
power inverter
output
is too low.
The battery voltage is too low. Recharge the battery.
No power to
inverter. Blown fuse. Replace fuse.
Buzz in the
audio system.
Inadequate internal power supply
ltering of stereo system. Use an audio system with a high-quality lter.
Television
interference. TV signals are weak.
• Adjust the orientation of the power inverter,
television, antenna and cables.
• Maximize TV signal strength by using a
better antenna and use shielded antenna
cable where possible.
• Try a different TV model.
The power inverter is equipped with protective shut-down features.
The details are listed in the following table:
PROTECTION
POSSIBLE CAUSE SOLUTION
Low battery
low-voltage
shutdown
Voltage drops to:
10.0–10.5 V = shutdown.
This protects the battery from
being over-discharged.
Recharge the battery.
High-
Voltage
shutdown
A defective battery charging
system can cause the battery
voltage to rise to high levels
(15.0–16.3 V).
Although the power inverter
has a protection against high
voltage, it might still be damaged
if the input voltage were to
exceed 16 V.
Disconnect the connected devices. Verify that
the charging system is properly regulated
and the battery is 12V nominal.
Overload
shutdown
If you connect a device that is
rated too high or a load that draws
excessive surge power, the
power inverter shuts down.
Use a product with a power rating within
the power inverter's continuous power
rating range (see Operation).
Overheat
shutdown
The power inverter shuts down
automatically if it exceeds its safe
operating temperature.
• Switch the power inverter off and
disconnect it from the 12 V outlet.
• Disconnect all connected devices and allow
the power inverter to cool for at least
15 minutes.
• Use a brush to clear any blocked ventilation
holes.
• Move the power inverter to a cooler
place. Reduce the load if continuous
operation is required.
