Connect VM140 to logic motor

Hi!
I have a basic question of how to connect digital output to the logical control inputs on a logic motor? The motor have external power, but don´t understand how to connect cables from VM140:s digital output to get a signal to let say “power enable” on motor. Is it not merely to connect output to power enable, and logic ground on the motor to ground on the circuit board output for a closed circuit, or? And the same way for more digital outputs to the motor?

And you can feel free to explain how can the clamp connection protects the circuit board.
