1. To prevent earth currents from flowing in the Triax system we recommend galvanic separation of earthed equipment connected to the camera This separation can be achieved by using an isolation transformer between the local power outlet and the equipment connected to the camera Alternatively use equipment that has a double insulation and therefore does not require an earth connection LDK 4502 TriaxHD Base Station User s Guide v1 0 Base Station earthing The rear of the unit has two separate screw terminals for protective earth PE and video earth A VE These are normally connected by a metal strap A VE Metal strap PE The protective earth terminal is internally connected to the protective earth conductor of the power cable In normal circumstances the connection between the protective earth and the video earth should not be broken If required the central earth connection wire of the studio can be connected to terminal PE in accordance with VDE regulation 0800 part2 Only if the studio or OB van is equipped with separate protective and video earth systems may the metal strap be removed Under these circumstances the video earth terminal must be connected to the central functional earth potential video earth of the studio This earth potential should have functional protective and noiseless earth FPE qualities as stated in the VDE regulation 0800 part2 A low impedance interconnection of both earth
