If you're not pressing the saw "ON" button, you're not sending power to the motor.? ?Note that running?a 3 phase motor on 2 legs won't hurt it, but trying to start?a 3P motor on two legs isn't a great idea and usually won't work.? Two phases usually lack the torque to overcome starting inertia, but once spinning, two phases just provide 2/3 power.? This is how the <$100 "phase converters" work.? They have a capacitor to give a short starting burst to the 3rd leg and then once spinning the they just pass the two legs thru ( a free?"phase converter" is tie a rope around the motor and manually start it, like a lawn mower)

So the way I tripple-check when wiring up a new plug is plug in the machine and see if the panels and controls work with the converter off. If it does, then it¡¯s being fed by the two pass-through legs, not the manufactured leg. But I would be very surprised if the panel would burn out that fast from just raising the blade height once, even if it was getting extra voltage by being wired incorrectly.?

CORRECTION.
Mac rousted me up this morning about wire colors and electrical connections to phase converters. ?I have documentation from Felder that suggests the brown wire should always be on the phase converter manufactured leg, Mac had contradictory information. ??I started to wonder if dementia was finally setting in. ? So I called Felder service in Delaware.?
Apparently Felder had been inconsistent over the years in connecting the AC cable to the control panel electronics within the machine. ?As such, it appears that some minds changed a decade ago about which color wire is connected to the control circuits of the machine. ? According to the service tech, the brown wire is supposed to be kept OFF the manufactured leg from the phase converter. ? I¡¯ve revised the write-up I posted previously and the corrected version is attached. ? Sorry for any confusion.
Phase converter outputs could be connected as follows if using plugs and sockets for 3-phase connections to the machine: ?T1 output connects to L1 on the receptacle, T2 connects to L2, T3 connects to L3. ?The brown wire belongs on L2, the black and grey wires on L1 and L3. ?The black and grey wires should be reversed if the motors are running backwards.
Sorry for all the confusion.

Oh no prob. I haven¡¯t touched it since I made this initial posting. I just hope my first fub up didn¡¯t destroy the control panel/power drive.

Re: I did something stupid!
Thanks Mark? A couple weeks ago I asked AR Th same question about were to land Manufactured leg on ?main 3 phase panel,? They said it made no difference.
?I asked Google few times but the NEC 408 did not come up ?I should have looked deeper into my NEC but not being a Electrican only a hack I landed on C with Red got that right any how. So 408 is clear and I shall change. ( weird thing about that is all my older machines and any industrial settings I¡¯ve been in Red is control wire . Mac,,,

The high leg conductor is to be red or orange.? ?In fact, some people call it the "red leg" because of this.

3) NEC says the high leg must be the B phase on panels:
408.3(E) Phase Arrangement. The phase arrangement on 3-phase buses shall be A, B, C from front to back, top to bottom, or left to right, as viewed from the front of the switchboard or panelboard.?The B phase shall be that phase having the higher voltage to ground on 3-phase, 4-wire, delta-connected systems.??
4) NEMA receptacle lugs are labeled X, Y, Z.? ?There is no code spec for mapping phases A, B and C to NEMA lugs X, Y, and Z.? But common sense is that the "middle" phase be consistent.? ?So the Y lug should be the high leg.

Re: I did something stupid!
So my wiring is OK.? I remember talking to one of the Felder techs from Delaware back when I received my KF 700 SP and he said the same thing David posted.? I was about to open up my PP and trace all my extension cords to make sure my personal note is correct.? Thank you for the verification.
BUT, Felder does not want you to open the electronic cabinet without their permission otherwise, you void warranty.? My machines have stickers all over the electrical cabinet with such warning.? I've stayed clear of it.? At least, until the machines are out of warranty.

Re: Replacement Nordfab Seal Material
I have yet to try this. A while back ago I bought a Fat Tire bicycle tube. Barely inflated its about 3" diameter. So it stretches. My thinking was to cut a strip maybe 1-1/2"w and place under clamp. It should fit the 5&6" diameters. There's also other sizes you can try.  Shouldnt this work or is it a corny idea? It's thin enough for the clamp to tighten. Doublke up if needed. Help seal the rubber grommet. No? If it does work, then you have enough to seal a bunch of seams.
