I cannot seem to get EU to get the multiblock spinning, does this not work both ways?

currently using IndustrialWires-1.7-31.jar

I think It might be useful to mark this in the manual for anyone else having the problem, it's not quiet obvious for non-professionals.

You will need to get the multiblock up to a decent speed using AC/FE, once it reaches that speed the commutator will convert the DC to AC for the coils to use (and for you to power your machines from). So you need some FE to start the conversion, afterwards it will run on just EU.
