KM6-II Subracks: Accessories PCB Grounding Clip KM6-EC This grounding clip can be inserted into the front or rear of 1,6mm pcb guides in KM6-II and KM6-EC subracks. compatible PCB Grounding clip Features Electrostatic Protection Occupies `unused' area of Eurocard No screws required The modification required to the pcb takes the form of a conductive strip along the edge of the board, either on the left or right side (see illustration). The clip has been tested to IEC 950: 1986 section 2.5.11. In testing, the clip reached a steady temperature of 76 degrees C at 15A, with a resistance path of 7m. A typical electrostatic discharge would be 12A for a period of 1 microsecond. It should be noted that the clip is designed to provide a ground path for electrostatic charges, not for a power short circuit or as a ground rail. Contents of kit Description Grounding clip Detail of grounding strip requirements on a standard Eurocard wiring and/or component side 0.5 1.5 2.5 Contacts on the clip provide electrical continuity between a suitably equipped Eurocard and, via a spring under the clip to standard front extrusions. Pcb's can, therefore, be grounded before the engagement of connectors. The clip, which is supplied in packs of 10, fits into a `pocket' in the guide and requires no screw fixings to maintain contact.
