The power supply to the system is switched on and the access doors to the hazardous area are locked closed.

The removal of the isolation key in the KSS, isolates the electrical supply to the LV Panel. This key is then used to unlock the D panel door interlock on the panel door.

The power cannot be switched on until the door is closed, the catch is trapped in the D panel door interlock and the key returned to the KSS.
