Hi Fernando,

Thanks for the feed back.

Both ground leads are connected together but that is not visible on the 
picture. Do you mean two cables that connect to the end plate?

Also here the two HV leads are connected together but that is not visible 
on the picture.

We start doing that after taking the picture and we indeed do not want any 
silicon based products. We use Scotch Weld DP-270 (black) to do this.

Cheers,
