I'd like to control my shop's 240V lighting via a 2477S, but I can't find any wiring diagrams on-line to show how to safely do this.
I'm in the US with single (split) phase power.
The 2477S is rated for 277V/1800W, so 240V/620W should be fine.
The switch box has 240VAC in (black/line1, red/line2, white/neutral, and bare/ground),
and 240V out to the lights (same wire colors, though white/neutral is capped off in the light fixtures).
Since neutral is unused by the lights, I should be able to wire the 2477S across one of the line/load pairs (the other line/load pair will be capped together).
So my real question is where to wire the 2477S's neutral line?
Does it go to the (otherwise unused) neutral?
Or to the un-switched line/load wire pair?
My hunch is that the 2477S' neutral should go to the real (unused) neutral so the wired communication protocol works correctly. I don't expect the switch will care if the "other side" of the load is wired to neutral or wired to the other hot line. But I wanted to confirm this and make sure I won't be running the switch out-of-spec or causing some other serious problem (I will properly label all the wires in the fixtures so it'll be clear which lines are hot and switched.)
Thanks,
