Connecting the ventilator of the SCR-485?

Dear all, yesterday I managed to get my new SCR-485 running and integrate it into Home Assistant.


The ventilator that is mounted on the heatsink is not connected yet so it does not run.

Can I connect the ventilator to the 220/230 V wires?

(on some pictures I saw here it looks like that)

Did you connect the ventilator parallel with the INPUT wires?

That way the ventilator will run all the time and at a constant speed?

Or to the OUTPUT wires?
So it only runs when the SCR-485 provides power and at a variable speed?

Thanks in advance!

The cooling fan is connected to the input terminal. If your installation environment does not have good heat dissipation.

I am going to put the SCR-485 in a protective box, because of the exposed 220/230 V connectors/wires.

So I will connect the ventilator like you advised.

And I will drill holes in the box to provide for fresh air flow.
