FX SYSTEM CONFIGURATION – SERIES/PARALLEL QUAD FX SYSTEM 
Series/Parallel Quad FX System 
The following diagram illustrates a typical series/parallel FX installation using four 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 120 amps AC or more.  The AC wiring connected to the QUO 100A dual 
bypass breakers must handle 100 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 8-14.4KW 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, MATE and X-240 must be connected 
to successfully stack these FX’s in series/parallel.  The MATE must be connected to adjust any parameters or to display any meters.  
Once the FX’s have 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:
  Program the top FX as the Master (1-2PH MASTER), the first Slave as an Outback L1 slave (OB Slave L1), and the second 
and third Slaves as OutBack L2 slaves (OB SLAVE L2).  See the STACKING INFORMATION section of the manual for more info. 
In systems that include three or more FX’s and must be series stacked, an X-240 autotransformer must be used.  When the FX’s are 
connected in series for 120/240 VAC, the X-240 can be connected to the two AC output legs to allow all 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 more of the FX’s.  The X-240 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.
