306:T. meas. The NT Solar Inverter is equipped with a
temperature sensor that monitors the
heat sink temperature. This message ap-
pears if the sensor reports a value outside
its value range or if the sensor cable is da-
maged.
The ambient temperature of the Solar In-
verter is outside the permissible range (<
-25°C).
Wait until the temperature is back in
the permissible range.
A cable break has occurred in the sensor
which monitors the heat sink tempera-
ture.
Please contact the Technical Hotline.
The phone number is provided on the
back of the manual.
307:Overtmp.
(Warning)
Your Solar Inverter is designed for an am-
bient temperature of up to +45?. When a
specified temperature threshold of the
heat sink is reached, the feed line is line-
arly reduced in size. Should the heat sink
temperature nevertheless continue to in-
crease, feeding is stopped. This warning
appears when the current heat sink tem-
perature is just below the switch-off
threshold.
The maximum permissible ambient tem-
perature has been exceeded.
The installation location is not suitab-
le. Please find another installation lo-
cation.
The air circulation requirement was not
taken into account during installation.
Clean the Solar Inverter, if dirt pre-
vents cooling.
Observe the installation distances
specified in the manual.
Objects were laid on the heat sink and
unimpaired convection was prevented.
Remove the objects.
309:control The software version of the control soft-
ware is incompatible.
Carry out a software update.
