I recently aquired this machine at auction. Thanks to all the support at this site I have replaced the hard drive with one off ebay. It is now showing a 4000f system fail, which is the dv5 board I quess. Here is my question, when I power up the machine the contactor that powers the dc bus is never engaged, the drives are showing undervolts - duh. All 3 axis appear to be at their limits. Do I need to manually move them off the switches before I can get them to power up? I cannot find any info in the schematic or manuals. I don't really want to screw this thing up if I can avoid it.

Any help is appreciated.
