[RE-wrenches] Outback Rapid Shutdown RTB rewiring

[cwarfel]

I learned from Outback yesterday that an important step in using this RS 
initiator is not described in the directions. The prewired GFI needs to 
be removed and the conductors connected to their supplied RTB breaker 
that is supposed to be located in the same slot. The GFI function is 
inthe combiner box.

Has anyone found Outback instructions describing this?  The person I 
worked with on the phone yesterday could not find any directions to this 
effect.  Chris
