Connecting a 24v Roland Mill

I’m trying to figure out how I go about using Fabman bridge with our Roland SRM-20 Mill.
It has an external 24v power supply, so would I make an extensioncord to the bridge and the powersupply or connect the 24v through the bridge?

You can use such an adapter cable and plug in the power cable of your mill then:

But that means anyone can bypass the fabman easily. I thought of a more permanent solution.
