Guest guest Posted September 18, 2006 Posted September 18, 2006 Lets see, the controller was on. (First thing I did wrong!) And I was connecting the grounds to each other. One of the grounds was touching the heatsing and when I got it to connect it, I thought I felt a slight vibrating like that was carrying power. So is their somthing their or was I probaly touching somthing else?---Daniel L
Guest guest Posted September 18, 2006 Posted September 18, 2006 Heat sinks are usually tied to chassis ground, and have no power to them. Maybe what you felt was a 60 cycle hum as the controller powered up.
Guest guest Posted September 18, 2006 Posted September 18, 2006 This is in the front of the instruction manual , I dont think you should be touching it with power applyed ."

Guest guest Posted September 18, 2006 Posted September 18, 2006 Technically you should be 99.9% safe touching the heatsink with power applied.It's that .1% that doesnt make it worth trying though for me! lolBetter safe than sorry everyone. Just unplug the darned thing when doing anything to it!Luke

Yes, I know ALL the warnings, I know the basics on home electrical systems, I know what electricty can do. And I take resposibility for my actions. Yes, I have been shocked a few times, most people here has been also! The only thing I do not know is what ine internal componets of a circut board are so.... Is a 60 Cycle hum the transformer getting jucied up?--Daniel L
Guest guest Posted September 18, 2006 Posted September 18, 2006 The heatsink should NOT be carrying any power. Are you using a metal enclosure, or plastic (or wood)? If metal, make sure you're using a 3-wire, grounded power cord, and bond the grounds to the enclosure (which should in turn be bonded to the heatsinks).If you're feeling a tingle, I'd be very wary that you're somehow getting live power there. Use a multimeter to test between the heatsink and a known-good ground. You shouldn't measure any voltage. If you do, something is bad -- don't use the controller until you figure it out!Are you saying that I dont know how to wire somthing up? I think he's saying it's generally a bad idea to be mucking inside an electrical enclosure with the power on... That same "tingle" can kill you if you had touched a good ground (like a water pipe, the outside of a grounded appliance, etc) with your other hand and the current be allowed to cross your heart...-Tim
Guest guest Posted September 18, 2006 Posted September 18, 2006 That would be correct Tim, it was meant to be a gentle reminder to be safe out there View at your own discretion
