RE: [CAD_CAM_EDM_DRO] Re: ELCB Issues

Trouble is we have no other choice but to use an EMC filter.

I have used a lot of Jaguar, Omron and Siemens inverters with and without
EMC filters, and for me they still tripped a 100mA ELCB with or without the
filter.

These were all new. We used to just have a spare supply on it's own ELCB
just for testing the inverters so it wouldn't knock all the rest of the
factory out.

Possibly one without an inbuilt EMC filter ;) Once fitted an inline
filter to an OLD Jaguar Cub inverter, that was enough to cause tripping.
Before it was OK.
