Configuration
The PSX-240-Relay must be connected to the AC output circuit of the
FX system and is intended for installations that include the following:
• An installation with two or more OutBack FX Series
Inverter/Chargers wired to produce split phase 120/240 VAC.
• The FX system is programmed using “OutBack” Stacking (not
“Classic” Stacking).
• AC input source to the FX system is either two in-phase 120
VAC circuits, 120/240 VAC split phase, or two phases of a
120/208 VAC wye-connected 3-phase source.
If your system does not conform to the configuration conditions
described above, please contact your dealer.
Note:
• The proper connections must be made in the field. This
information is located in the MECHANICAL INSTRUCTIONS
section of this manual.
• The FX system must be programmed in order for the PSX-240-
Relay to disconnect properly. This information is located in the
PROGRAMMING INSTRUCTIONS section of this manual.
Step Down/Balancing Configuration
The step down/balancing configuration for the PSX-240-Relay allows
large 120 VAC loads on one leg to be powered by FXs on opposite legs
(step down). It also allows each FX to produce the same amount of
power even though the L1 and L2 legs may have different power needs
(balancing).
When an AC input is not present, 240 VAC between legs L1 and L2 is
applied to the 25A breakers of the PSX-240-Relay. 120VAC is then
available from either L1 or L2 to system neutral.
