Important information
xi
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.
