Default Final Stage of Building UcD400

Hello,

I'm now finishing my UcD400 amp recently bought from Hypex Electronics, I've noticed from the manual that there is an /ON (on internal pull-up) pin on the 4-pin connector, to be connected to the supply ground to a switch...

What will be the different between opened and closed switch for this signal?

Thanks,
RR.

This pin must be connected to ground to power-up the module. Open switch will power-down it. I think it's a very useful tool for delayed start, when PS is stable.
If you have multiple modules it is recommended to make all "ON pin" wires of equal lenght.
Am I wright?

Hope this helps.
Best of lucks.
