Is there any danger in running the L1-L2, L2-L3, L3-L1 outlets?  It's 3-phase and I have heard horror stories about how unbalanced loads can destroy transformers and other components in power supplies and computer components.  I worry about having one miner stop for some reason and the load hurting the other two or some combination thereof.

What errors should I be receiving with the 120v input?  So far I've been mining for 5 days like this and the hashrate's been constant and I don't see any obvious errors under the Miner Status tab in each S9.  I've attached a screen shot of one of the S9's status, they all look pretty much the same with similar numbers and they all have "oooooooo"s.
