TROUBLE-
ShOOTING
If one of these problems occurs, disconnect the
external devices from the voltage converter and
disconnect the voltage converter from power.
Error/problem
Possible cause
Remedy
Device isn’t working.
Battery voltage below 9.5 V �0.3 V.
Replace or charge the battery.
The power draw of the connected
device is too high.
Disconnect the external device.
The maximum power draw should not exceed the power
rating of the voltage converter.
Device operation was interrupted by
one of the safety systems.
See „Technical characteristics“.
„Error“ LED [25] is
lit red.
The housing temperature is above
60 °C.
• Check if the voltage converter is cooled adequately
and the vents are clear.
• Let the device cool down and provide sufficient
ventilation.
The input voltage is too high;
Overvoltage protection
Examine the input voltage.
The input voltage is too low;
under-voltage protection.
Examine the connection and charge the battery.
The rated power exceeds the ma-
ximum total power rating; overload
protection.
use devices with a rated power which does not exceed
the power output of the voltage converter (see „Tech-
nical data“).
Short circuit in the device
Examine the connected devices. Do not use the concer-
ned devices.
