10.1.3 Voltech Safety Interlock Cable
The Safety Interlock Cable is a robust and convenient way of connecting the AT3600 and other Voltech products to a safety interlock system. Although other safety systems may be suitable, the cable has been optimised for direct and quick connection to the Banner product described in the previous section.

Principle of Operation
The cable carries 3 pairs of color-coded wires. Each pair must be linked together by the safety system before the AT3600 will operate a high voltage test. If any one of the three pairs is becomes un-linked during a test, the AT3600 very quickly switches off any high voltage that is being produced.
There are three pairs of wires in order to provide the multiple redundancy required by various international safety standards.
