Earthing and protecting the system
The protective earth and equipotential bonding are important integral parts of the
safety concept: Standard EN 60950 relevant to safety matters stipulates protective
earthing.
Warning
High leakage current.
Establish an earth connection before connecting to the telecommunica-
tions network.
Disconnect the system from the telecommunications network before car-
rying out maintenance work.
Warning
Overvoltage.
Transient overvoltage can occur on the mains and on the telecommuni-
cations network.
Protect each line installation leading from the building by using one
surge voltage protector per core at the isolating point (main) distribution
frame or entry point into the building.
Operation on an IT current distribution system
This system can be operated on an IT current distribution system with voltage up to
230 VAC.
