IMPORTANT NOTE:
NEVER connect or disconnections any wire while power is applied.
ALWAYS disconnect power before making any connections or disconnections.
Failure to do the above will result in damage to the stepper drivers.
Note: Any Mains power connections must be installed by a Licensed electrician or suitability qualified person.
