Abstract

Provision is made for removal of prime power from an electronic assembly for servicing purposes. Service personnel can be exposed to hazardous potentials if assemblies can be accessed while primary power is still applied. This can be prevented if primary power is removed in the process of accessing the assemblies. As shown in the drawing, an input power connector 1 is an integral part of a hinged cover 2 in a printed circuit (P.C.) assembly. The assembly can only be accessed by disconnecting the input power connector 1, removing the fastening screws 3 and 4, and swinging hinged cover 2 down. Power connector 1 cannot be reconnected unless hinged cover 2 is closed back in place.
