Equipment provided with one or more plug-in units

Abstract

Equipment including at least one plug-in unit and a body device for receiving the plug-in unit is presented. The plug-in unit includes an electrically conductive structure (121, 122, 123) having at least one surface area capable of forming a capacitive coupling with a surface area of an electrically conductive part (130, 131) of the body device when the plug-in unit is inserted in the body device. The equipment further includes a monitoring circuit (124) for generating a signal indicative of electrical properties of a measurement circuit including the capacitive coupling and at least one galvanic contact provided by electrical connectors of the plug-in unit and the body device. The generated signal is also indicative of correctness of the installation of the plug-in unit. Thus, the correct installation of the plug-in unit can be electrically indicated and monitored.
