Abstract

The mounting rack (BGT) has plug-in printed circuit board assemblies (BG) with an electrical resistor (R) between the front panel (FP) and the sliding contact (K). Any electrostatic charge applied to the front panel (FP) is damped by the electrical resistor (R) before being dissipated to the mounting rack BGT. The novel mounting rack (BGT) has the advantage that an assembly (BG) can be inserted and withdrawn even while the other assemblies in the mounting rack (BGT) are in operation, without any interference signals that could adversely affect operation of the other assemblies in the mounting rack (BGT) being emitted.
