Hello!

I am installing a magnetic lock on one of my doors and have have a question on the wiring.
Here is an image of the wiring instructions I am looking at.

My question is does this diagram mean that I should have a wire going from the negative insert on the terminal block to the positive insert on the door lock?

Or should I connect the positive insert on the door lock to the negative on the power supply?

Any help with this is appreciated!

You have a terminal block. Battery+ goes to terminal 4, battery- goes to lock, -wire from lock goes to terminal 3.
