Disclosed is an arrangement of a foolproof way of never opening an electronic device with the power cord connected.

First described is an arrangement of the interface panel (see Fig. 1). In previous designs the interface (I.O.) panel 1 has been an integral piece of the base 2. The base is the mounting area for the printed circuit board 3 and expansion cards 4. The expansion cards 4 then are mounted onto the I.O. panel
1. A problem occurs when there is a family of electronic products with each product having different electronics and different connector openings whereas holes in the I.O.

panel are different conventionally, meaning a different base. Having the I.O panel 1 as a separate piece allows usage of the base on any product desiring it with no changes. Changes because of electronic requirements occur only in the
I.O. panel 1, offering lower cost. The I.O panel is connected to the base by way of a groove 5 provided by the base 2 and securely anchored by a screw 9.

Following is a description of location of the power cord connection for optimum safety access. Service to the electronics is by removal of screws 6 in the I.O. panel 1 and lowering of the base 2 about pivot 7. The power cord connector 8 is located such that when connected the connector blocks access to the removal screw 6 in the I.O. panel 1 whereas no access to the electronic is possible without removal of the power cord connector 8. See Fig. 2. The power cord can...
