Abstract
The use of dead-front construction and other means of segregating higher-voltage portions of control box circuitry with carefully planned use of test points, an in-place schematic diagram, and indicator lights, are explained in this paper. Sensitive circuitry for personnel protection is discussed. The reception by manufacturers and mine personnel of the ideas as embodied in a demonstrator unit is summarized. Recommendations to improve maintenance safety are listed and discussed.
