FX SYSTEM CONFIGURATION - PARALLELED QUAD FX SYSTEM
Paralleled Quad FX System
The following diagram illustrates a typical paralleled FX installation using four FX’s. For this type of installation, use of OutBack Power
Systems PS system is recommended. This FX system will require one AC-IOB-60Q bypass kit. The AC-IOB-60Q bypass kit includes
two QOU 60 amp breakers for the bypass and four 30 amp CBI breakers for the AC outputs. The quad FX system will require four
additional CBI 30 amp breakers for the AC input. Additional breakers can be purchased and installed in the PSAC if necessary. The
AC wiring from the AC source and to the AC loads must handle 120AAC or more. The AC wiring connected to the QUO 60A dual
bypass breakers must handle 60 amps AC or more. All other AC wiring must handle a capacity of 30 amps AC or more. This type of
FX system can continuously power 8-12KW 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 parallel. A MATE (through the HUB if one is needed) must be connected to adjust any parameters or to display any meters.
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.
The diagram below represents parallel stacking of four FX’s.
Program the top FX as Master (1-2PH MASTER) and the three lower FX’s as OutBack L1 Slaves (OB SLAVE L1)
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.
