This wiring is 24VDC to tell the maintenance bypass switch to go to utility power because the UPS is kapput.Doesn't leave you a lot of options. Can't even use EMT or a flexible raceway. My guess is whoever wrote it is pretty much clueless. You might want to just call them and ask about it. Maybe they have an updated instruction.
On the other hand, is there some reason why this can't come in the same conduit hole as the power wiring comes in?
It also seems to me the instructions would allow you to run it in PVC conduit.
