will increase. The temperature of a critical hot spot inside the inverter is monitored
and at 95° C, the AC output of the inverter is shut down temporarily. The Status LED (2)
will turn oRANGE and a buzzer is sounded. The GREEN indication light on the GfCI will
be off.
The unit will automatically reset after the hot spot has cooled down to 70°C.
Reverse Polarity at the Dc input terminals
The Positive of the battery should be connected to the Positive DC input terminal of the
inverter and the Negative of the battery should be connected to the Negative DC input
terminal of the inverter. A reversal of polarity (the Positive of the battery wrongly con-
nected to the Negative DC input terminal of the inverter and the Negative of the bat-
tery wrongly connected to the Positive DC input terminal of the inverter) will blow the
external / internal DC side fuses. If the DC side fuse is blown, the inverter will be dead.
The Status LED (2) and the GREEN indication light on the GfCI will be switched off and
there will be no AC output.

Reverse polarity connection is likely to damage the DC input circuitry. The
internal fuse(s) should be replaced with the correct size of fuse shown under
specifications. If the unit does not work after replacing the fuse(s), it has been
permanently damaged and will require repair / replacement (Please read
Section 11 - "Troubleshooting Guide" for more details).

cAUtion!
Damage caused by reverse polarity is not covered by warranty! When making
battery connections on the input side, make sure that the polarity of battery
connections is correct (Connect the Positive of the battery to the Positive termi-
nal of the unit and the Negative of the battery to the Negative terminal of the
unit). If the input is connected in reverse polarity, DC fuse(s) inside the inverter /
external fuse will blow and may also cause permanent damage to the inverter.
