Hi Mark,
you didn't seem to get any responses, so I thought I'd comment.
The equipment maintenance guy is correct, you can remove the frame and
connect each anode and work rail by individual cables. The normal routine is
to use solid busbars to the non moving part of the agitation frame and cable
from there. Most people try to connect both ends of the anode rail by cable,
and similarly the work rail, as this gives 2 points of contact on each
rather than just one, and it appears to even out the current. I think it
adds a further complication, as a poor connection will create a hot spot and
reduce the current going to the product. At least with just one connection,
if it's faulty you know about it (voltage rises on the rectifier).
