Zusammenfassung:An industrial system includes a load control assembly, an integrated absence of voltage tester (AVT), and an absence of voltage indicator. The load control assembly has a supply input, a load output, a disconnecting device, and a load controller coupled to the load output, with the disconnecting device coupled between the supply input and the load controller. The AVT is integrated into one of the disconnecting device and the load controller, and the AVT configured to detect an absence of an operating voltage of the load control assembly. The absence of voltage indicator is coupled to the AVT and configured to indicate the absence of an operating voltage of the load control assembly detected by the AVT.
