TCP 121 Turbomolecular pump controller power

Hey community!

I have a couple TCP 121 Pump Controllers with their ridiculous 16-pin interface connectors. According to the manual, attaching 110 vac to the following pins should cause the controller to come on:

Line  ->  b2

Neutral -> a2

Gnd -> a8

None of the controllers are coming on and I am not sure if they are broken. I got them second hand but the possibility that they are all defective worries me.

Is there any other connections that need to be made? Are there two other pins that need to be connected to get them on?

Thanks y'all!
