The M12 Interlock adapter is used to connect an emergency-stop button to a MG Master LV.
When the emergency-stop button is pressed the MG Master LV will open its main safety contactor immediately and goes to the failsafe state.
The M12 interlock adapter may only be used to open the main safety contactor in case of emergency.
 
The M12 Interlock adapter consists of three connectors:

2-pin green terminal connector
