Does it matter which way around you wire the AC side of the SSR.
That is which contact is live and which is load or can they be wired either way around?
I’m mounting my two SSRs end to end with the AC ends together so am supplying live feed to pin 1 on one and pin 2 on the other. I trust this is OK.
Live to pin 1 on SSR Cool, Pin 2 SSR Cool to compressor (cooling circuit)
Pin 1 SSR cool (Live) to Pin 2 SSR Heat
Pin 1 SSR heat to heater
Just checking - I have had to change my wiring plan and am trying to keep it neat and safe.
