10.7 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 connected to the Negative DC input terminal of the inverter and the 
Negative of the battery 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.

 INFO
 

Reverse polarity connection is likely to damage the DC input circuitry. The

 

 internal fuse(s) should be replaced with the same size of fuse(s) used in 
the unit. If the unit does not work after replacing the fuse(s), it has been 
permanently damaged and will require repair / replacement.

 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 terminal 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 and external fuse will blow and may also 
cause permanent damage to the inverter.
