Hi guys, it's been a long time since I have posted to RCM, I mostly lurk.
I come begging for some of the group's wisdom.

I have a friend who has purchased an old Mori Seiki SL-3B Lathe with
Fanuc 5T control for his high school shop. Since it was made in Japan
many years ago it did not come with UL or CSA approvals, something that
is required before it can be hooked up in the school. (BC Canada BTW) The
normal procedure for imported machinery is to get an approval sticker
from the local electrical inspector.
He has done a preliminary inspection and stated that he requires an
insulation test of 2x the supply voltage plus 1000v for one minute,
during which time he checks for insulation breakdown and listens for
arcing. I assume he will be using a megger. We're a little reluctant to
allow 1400 volts to be applied to the input, parts for this age machine
aren't easy to come by. He said boards may be removed during the
testing, but that still leaves the DC spindle drive and servo power
supplies. I do not know if the rectifiers can handle that much voltage.

Is this a reasonable method of testing what basically amounts to a
computer? Is it going to kill some part of the machine?

Thanks,

Mike
