You sir..are correct!
The clue I should have guessed was that the LED on the SSR was not illuminating...LEDs are polarity sensitive!
The image I was going by (duet3_mini5+_v0.5-v1.02_d1.5_wiring.png) was upside down as viewed on the screen, as opposed to the direction I have it mounted. GREAT CATCH!
Board now heats up (quickly I might add) and the LED on the SSR is aglow!
