Multiple EMI filters versus a single filter for multiple drives

[johnsattuk]

Not sure how sensitive they are, told to keep away from arc welding and large motors, domestic microwave OK, vacuum cleaner OK

I think it is a distance related effect, leaning on a power drill probably not a good thing, the pacemaker itself I believe is quite well protected, it's the wires (arials) into the heart which pick up the EMI.

It's a robust steel cabinet but doen't have a metal to metal contact all round, will have to look into that, have fitted EMI screens to fan inlet and outlet, and I always use an abundance of ferite filters on the cables

Have rejiged my my cabinet and I am going to fit seperate two stage filters, don't want to pop off sooner than I need
