Hi guys, I have had my Haas tm1 in the garage for a year, and just moved to a small unit with a 3 phase power supply.
I have gone to wire in the Haas according to the manual and noticed some queries id rather check before putting power to the machine and letting the smoke out.
Previously on single phase live went to L1, neutral to L2. This isn't in the manual, but it had been done by the previous owner and it worked fine.
The Haas tm1 manual suggests on three phase live goes to L1, L2 and L3...and no neutral is wired in.
That would seem ok for a Wye setup (think that is what it is called), except in the old setup L2 was neutral, and now it's live....that seems like I'm about to have a very expensive bill.
The electrician I had is not used to 3 phase not running a neutral and suggested I ask around before causing expensive damage.
A complicating factor is that in the UK our three phase is 400v, not 200v, so the manual reads wrong already.. so that undermines my confidence.
Any advice please? Thank you
