FX SYSTEM CONFIGURATION – SERIES OR SERIES/PARALLEL DUAL FX SYSTEM 
Series or Series/Parallel Dual FX System 
The following diagram illustrates a typical series FX installation using two FX’s.  This diagram is for a non-Mobile FX installation 
only.  Below this diagram are notes for how to change this diagram to accommodate a Mobile installation.
 The AC wiring from 
the AC source and to the AC loads must handle 50 amps AC or more.  All other AC wiring must handle a capacity of 50 amps AC or 
more.  For a ‘Mobile’ FX system, 30A input breakers should be used due to the maximum AC input pass-through rating of the Mobile 
FX’s.  This type of FX system can continuously power 4-7.2KW of loads depending on which model is used.  Connecting more power 
than the continuous rating of the FX may cause breakers to trip or the FX to shut off its AC output.  A HUB and a MATE must be 
connected to stack these FX’s in series.  The MATE must be connected to adjust any parameters or to display any meters.  The slave 
FX must be programmed through the MATE as a ‘Classic Slave’ (series stacking, no X-240) or as ‘OB Slave L2’ (series/parallel 
stacking, X-240 included).  Once the FX has been programmed using the MATE, the MATE can be disconnected.  The programming 
will be saved within the FX’s non-volatile memory even if the FX is completely shut down.   
 
NOTES:
  The X-240 autotransformer (located at the top-middle of the diagram) should never be used in a system that is programmed 
for “Classic” stacking.  If an X-240 is connected between two 120 VAC output legs, program the top FX as Master (1-2PH MASTER) 
and the lower FX as an OutBack L2 slave (OB SLAVE L2).  If the X-240 is not included in the system program the top FX as Master (1-
2PH MASTER) and the lower FX as an OutBack L2 slave (OB SLAVE L2).  See the STACKING INFORMATION section of the manual 
for more info. 
When the FX’s are connected in series for 120/240 VAC, the X-240 autotransformer can be connected to the AC output to allow both of 
the FX’s capacity to be available on either of the 120 VAC output circuits.  This allows higher efficiency and better performance as 
heavy 120 VAC loads are powered by both of the FX’s.  The X-240 autotransformer also allows the master to power loads on either of 
the 120 VAC output circuits with the slave off.  This reduces the idle power consumption and improves the system efficiency. 
NON-MOBILE FX NOTES:  
The AC OUTPUT NEUTRAL IS NOT BONDED TO THE CHASSIS OR THE GROUND TERMINAL of 
the FX system.  This connection is to be made by the installer either in the AC service entrance or within the AC load distribution panel 
of the electrical system.  The AC input, AC output and DC terminals are isolated from the metal chassis of the FX. Proper grounding of 
these circuits and the chassis of the FX is the responsibility of the installer.  
MOBILE FX NOTES:  
The AC input source to the FX (grid and/or generator) must have an internal neutral-ground connection.  On 
the above diagram the AC source’s neutral conductor must go directly to the FXs AC NEUTRAL IN terminal or to a separate neutral 
busbar that is isolated from the FX’s AC output neutral.  The AC output of the FX must go to a separate AC output busbar that is 
isolated from the AC input neutral.  A bypass mechanism must bypass the AC source’s hot and neutral wires.  Proper grounding of the 
DC circuit and the chassis of the FX is the responsibility of the installer.
