Hi, I have a keling power supply kl- 7212. I have the input into the transformer wired for 110v (2 reds joined together, 2 blacks joined together). The output from the transformer is 2 blue wires, then 2 green wires. Where do these go? I assume that 2 or more of them go to the ac input on the voltage converter to dc, but I do not know which. I have not found any help on the keling site.
Thanks, Paul
