I recently bought 3 EDI Scrimmer II dimmer packs from an auction and had a few questions and curiosities. There are two 6k 6 channel units, and one 6k 12 channel unit, the 12 channel unit doesn't have a panel in the front to configure the pack for single or three-phase. The manual isn't much help with the initial wiring of these things. Am I just stuck with three-phase on the 12 dimmer pack? It seems like that would be kind of odd if that were the case, but it wouldn't surprise me. Is there any big and/or common issue with the modules or packs that I should be aware of, other than issues with age? Any info about these packs in general that cant be picked up from the manual is welcome.
