Hello,
How would one connect a dust collector to mesa 7i76e.
Its an 360V old unit.

I would like to wire it so its also possible to run with native on / off switch not only through relay.

Any wiring schema or comment welcome.

A DC coil relay would work to control the dust collector.

See the output section here.

Two relays might be needed, a small one driving the big one, but that depends on power draw and since we do not know the power draw, this is only a guess.

I would use a cheap SSR. One of the 40A ones that are generally good to at least 8A :-)

3 phase power = 3 SSR
Again this is just a stab in the dark as i am not sure if the blower is 3 phase, just assuming it is.
