Hi All!
New to the forum and working on refining an EV Kart I recently put together, but have some questions regarding wiring in a contactor and how to do so correctly. Couple build overview specs:
There is no DC/DC converter on this build so I am needed to switch the contractor using full pack voltage. Where my confusion is coming into place is am I needing to use a key switch that is rated for 72v DC? Finding a small rocker switch rated for this is proving difficult so it has me questioning my path in accomplishing this. I'm attaching some wiring diagrams I've come across that mostly reference the 48v TopKart system, but the theory behind my build is similar.
Additionally, if anyone is familiar with the EM200, is it the E-Lock wire I can use as the key switch? I haven't brought out the multimeter to test this yet, but if anyone happens to know.
Thank you!
