PARALLELED QUAD FX SYSTEM
• All AC wiring from the AC source and to the AC loads must collectively handle 100 amps AC or more.
• All other AC wiring must handle a capacity of 30 amps AC.
• This system can continuously power 8-12kW of loads depending on which model is used.
• Connecting more load than the continuous rating of the FX may cause breakers to trip or the FX to
shut off its AC output.
NOTES: Program the lowest-installed FX as Master (1-2ph MASTER) and the three remaining FXs as
OutBack L1 Slaves (OB SLAVE L1). The Master FX must be plugged into Port 1 of the HUB.
3-PHASE FX SYSTEM
• This system produces 230VAC per phase and 400VAC from phase to phase. There can only be one
FX per phase on a 3-phase system for a maximum of three FXs total.
• The AC wiring from the AC source and to the AC loads must handle 30 amps AC.
• All AC wiring must handle a capacity of 30 amps AC.
• This system can power continuously up to 6-9kW of loads depending on which model is used.
• Connecting more load than the continuous rating of the FX may cause breakers to trip or the FX to
shut off its AC output.
• The jumper in the HUB must be moved for 3-phase confi guration (please see the HUB Installation
and User Guide). The Master FX must be plugged into Port 1 of the HUB.
NOTE: Program the bottom FX as Master (3ph MASTER) and the upper two FXs as 3-phase Slaves
(3ph SLAVE). Keep the phases in order: phase one is connected to the FX programmed L1; phase
two is connected to L2; and phase three to L3 (or phases A, B, and C to inverters A, B, and C) as
shown in the diagram on the following page.
