How exactly is the PC & the servo's fed, is it fed across two phases? If so, this is equivalent to 1 ph, Usually these are on single phase so there is often a local 240 or 120v 1 phase set up sometimes with a local grounded neutral.
The reason I ask, is if it is just a question of preventing brown-out on the PC/Servo, and they are on a single phase set-up,(i.e. neither on 3ph) it may be cheaper to put a Sola Constant Voltage transformer just for these items.
Or wire an isolation transformer after the disconnect that is on the 240 1ph legs and feed both the servo's and PC.
