An Interlock is 1) the state of two mechanisms or functions mutually dependent; 2) on a high voltage area shield to prevent them being opened while the power is on, ensuring that the system remains closed.
Reference Definition by Aiche.org: Interlock is a protective response which is initiated by an out-of-limit process condition. Instrument which will not allow one part of a process to function unless another part is functioning. A device such as a switch that prevents a piece of equipment from operating when a hazard exists. To join two parts together in such a way that they remain rigidly attached to each other solely by physical interference. A device to prove the physical state of a required condition and to furnish that proof to the primary safety control circuit.
