ABSTRACT:
An electronic module configured to removably receive a power cord is provided with an interlock mechanism that prevents the power cord from being attached or removed while the module is in a power-on or current-drawing condition. The electronic module includes an on/off switch that, when in its on state, places the electronic module in a power-on condition. A guard mechanism is mounted to the electronic module, proximate the power switch, and is movable from a first position that captures and holds the power cord in connected condition with the electronic module, or prevents connection with the electronic module, to a second position permitting removal or connection of the power cord. Movement of the guard mechanism from the first position to the second position is permitted only if the power switch is in an off state.
