LDK 8000 HDTV camera system User’s Guide (v3.0) 11
Base Station earthing
The rear of the unit has two separate screw terminals for protective earth (PE) and video
earth (VE). These are normally connected by a metal strap.
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 conductors must
be provided at the central studio earthing point.
