PSX-240 Wiring

Post by JCO »

Greetings.
I recently purchased a PSX-240 for the step-up to 240 VAC feature. After combing through the manual, this and several other forums, I have been unable to find any clear wiring diagrams that show how to wire the two FX3048MT 120VAC outputs to the transformer.
Suggestions?

The wiring depends on what your are trying to do... ?

Are you Outback Stacking?

Kent;
Thanks for the manual link.
Steve;
I am attempting "series/parallel stacking, PSX-240 included" as described in the FX Series Manual. The thing that has thrown me was going from the X-240 to the PSX-240, where the instructions in the PSX-240 manual are somewhat obfuscating to my poor ol' brain, so please excuse my confusion. In looking again at the instructions of the FW-IOB-D-120/240VAC, I find a better representation of how to hook up the PSX-240:

I reckon the intent of this forum is information sharing, so anyone else searching as I am can find expert answers within these threads. Any further references are most appreciated.
Cheers;

Clive,

The drawing you linked to is easier to follow and it is just what you need for an "Outback Stacked" pair.
