Ok, here is what you have to watch out for: The pack may be designed with a common neutral. If this is the case, it will not work for you. In order to work you need to find out two things;
1) Does it use a common neutral buss or can the individual channels be isolated from each other?
2) Is there a separate ramp generator for each
channel?
The second question requires a little explanation. If the unit was only designed to work on one phase, there may be only one low voltage transformer feeding the control
circuit in the pack. This would be a problem. The control circuit looks to the ac output waveform of the transformer to find its zero voltage crossing point. It uses this point to time the waveform and chop it correctly. You need this for each phase. Some packs only have one. Some packs have three, and some packs have one for each channel. (One per channel is the best.) If each module is electrically independent, including a separate low voltage transformer, than a qualified technician could modify the pack for you. If there is only one ramp generator with one low voltage transformer, then you are condemned to single phase power even if the channels can be isolated. Problem is that if you plug into two outlets, they may not be on the same phase if the building is wired for three phase power. So what happens? Your light will come on to 33% or 66% with the
dimmer control set to zero! As you move the fader up, it will go to 100% then blackout, and the start coming up again, stopping at 33 or 66% at full up!
Please, Please make sure that whoever does the work for you is qualified. Also, remember that when you modify any equipment in this way, you void its UL rating. That can become a liability issue. Generally, this is never recommended.
