Mesa 7i76E HY Spindle Coolant Best Practices

I'm running the Mesa 7i76E with a HY water cooled spindle connected.

What would be best practice to wire my 12V fans and pump to automatically start when the spindle is enabled?

I am aware of the PD050 setting to number 1 which is a out of the box setting.

Do I need to use a 24V relay or will the 7i76E handle 12V ?

Thanks.

What voltage is the 7i76E powered with?

OK, 24V and max 30mA directly or 60mA with a diode across the relay coil, minding the polarity.
Or, if using a really small relay, adding a resistor in series with the coil is still manageable for 12V relay.

What about using the HY inverter? Any options there?

Or even better what if I were to use something like this:   www.amazon.com/Converter-DROK-Adjustable...ormer/dp/B08RBN31DT/

Connect it to the inverter 24v and use the built in inverter relay to switch on my water pump?

No idea if HY can do that, installed one of those once a few years back, but never checked if it can do that.
Some can by using the "at speed" output on the VFD so no need to wire anything to Mesa at all.
