Wiring a solid state relay

I can’t really take a usable picture as the relay is at the bottom of my enclosure, So, that being said, using the relay at the bottom of this post to start and stop my Dewalt with my G-Code…here is how I have wired it up: On the power supply where I marked an “A” the positive wire goes to the Arduino header pin 11. The ground wire goes to the Arduino ground. On the power supply where I marked a “B” the positive goes to the positive relay input and the ground wire goes to the ground input on t…
