XW generator start question [RE-wrenches]

[William Miller]

<x-flowed>

Dan/Jay:

This quirk may actually be a "feature."  This might allow one to use the 
Grid input as a second generator input.  If the auto start circuitry is 
independent of the Input 2 voltage sensing, one can connect a generator to 
either or both AC inputs.   Coincidentally, we are installing our first XW 
this week and may need this option.

Next question:  Can one install two GSMs????
