I have a bunch of defective electronic equipment out of Felder machines, and some repair bills that refute Mr. Dingus¡¯ claim that "
The high leg's position does not immediately cause any problems?¡°. ? It¡¯s a shame that Felder lets employees make such claims as their equipment does NOT include internal voltage regulation and will definitely let ¡°sensitive electronics¡± fry with voltages above about 245. ?This is not generally an issue when using a Phase Perfect, which is who this choice is ideal. ?But I can guarantee you that rotary phase converters can often output voltages in the 260-270 range on the high leg during high-current draw during motor startup.

As I had one response from Felder¡¯s tech support and a different response from the sales rep, I asked Mr. Dingus for clarification. His response is below. Note that my question for him was in regards to a specific machine (Format-4 Kappa 450 x-motion).

He does explain how to check the wiring. As I understand things, opening the electrical box on Felder tools voids the warrantee. I suppose I can ask for permission to do so once the machine arrives.

Note that ?he says it does not make a great deal of difference where the manufactured leg is connected.

Hi John,
Most?of our machines connect the brown power cable wire to Leg 2 inside the machine as shown in her picture, but not all. Yours happens to be one of the exceptions. The high leg's position does not immediately cause any problems though. For some components being connected to the high leg can slightly reduce component life span. Generally we have 2 legs of power that go to the control electronics and 1 that mostly only goes to the motor, and we put the high leg on the wire that just powers the motor. That keeps it away from the more sensitive electronics. This is essentially extra?protection for the longevity of the parts, not a requirement for them to run. We still recommend putting the high leg on Leg 2 to ensure maximum life span but connecting to a different leg wouldn't prevent the machine from running.
If you'd like to be 100% sure you can open the electrical panel on the machine and trace the power cable's wires back into the panel. They will go from your shop, to the on / off power disconnect switch on the chassis, then to DIN rail terminals labeled L1, L2, and L3. You're looking for the wire connected to the L2 terminal.
Best Regards
Phillip Dingus
