The AUX+ and AUX– terminals are a switched 12 Vdc supply.  The AUX can respond to many criteria 
and control many functions.  These include cooling fans, vent fans, load diversion, fault alarms, and 
automatic generator control.  The AUX output can also be controlled externally through the system 
display.  (For generator control, see the next page.  For all other functions, see the system display 
manual and the International Series GFX Operator’s Manual.)  The AUX can only control one function at 
a time.   

The terminals can supply up to 0.7 amps at 12 Vdc (8.4 watts).  This is sufficient to drive a small fan, or a 
relay which can control a larger device.  The terminals accept up to 2.5 mm2 (#14 AWG) wire.   

The AUX circuit contains electronic overcurrent protection, which resets after being overloaded.  No 
additional fuses are required for the AUX terminals. 

 

 

In this example, the AUX 
directly drives a 12-volt vent 
fan.  The + and – wires on 
the fan are connected to the 
AUX+ and AUX– terminals. 

The AUX LED 
illuminates when the 
AUX output 
becomes active. 

In this example, the AUX drives a relay that 
diverts wind power.  The relay’s coil is connected 
to the AUX+ and AUX– terminals.  When the AUX 
closes the relay (based on battery voltage), the 
relay diverts the excess wind power to a water 
heating element.  

Note:  Relays and elements shown are examples only 
and may vary depending on the installation.
