The AUX terminals can be used to perform “two-wire” generator start.   A two-wire-start generator is 
the simplest type, where most of the circuits are automated.  It usually has a single switch with two 
positions that is turned ON to start, OFF to stop.   

Either the system display or the FLEXnet DC can be programmed to perform automatic generator start 
using the AUX terminals.  See the system display or FLEXnet manuals for programming instructions. 

The 12 Vdc signal provided by the AUX can be switched on and off to provide a start signal.  It is not 
usually recommended to connect the AUX directly to the generator, but to energize a 12 Vdc 
automotive or similar relay with it.  (Depicted is the OutBack FLEXware Relay Assembly, which is sold 
for this purpose.)  The relay contacts can conduct power to start the generator from the battery (or 
whatever source is used).   

The drawing below is one example of a possible arrangement.  Specific arrangements, relays, and 
other elements depend on the requirements of the installation and of the generator.  (Note that it is 
more common for the battery to be incorporated in the generator.)
