The installation connector is IP20 protected (only when mated with strain relief housing (these installation connectors are not intended for use in easily accessible areas!)). This means that you cannot reach energized contact elements with your finger. The standardized KNX interface stands for a uniform and manufacturer-wide communication protocol for the intelligent networking of modern building and building system technology. The standardized WINSTA® KNX installation connectors in green are used for signal transmission in KNX networks.
