Filter 17.2.3.1.14 Shield Termination Termination of RF shields is extremely important in the reduction of RF emissions. The RF shields should be terminated at the entrance to the enclosure with a 360 degree contact between the shield and the enclosure wall. PACSystems* RX3i System Manual Appendix GFK-2314T Sept. 2019 Product Certifications and Installation Guidelines for Conformance 863 Compression Connectors Compression connectors are standard hardware available for the termination of conduit. The diameter of the connectors is not of significant importance other than to make sure the wires can actually fit through them. The compression connector provides a metal ring for shield termination and compression.
