8.1 Grounding and Safety
Safety Information Concerning the Grounding of Terminals
Danger of Point-to-Point Connections Between Separate Buildings
Care must be taken when XBT terminals are directly connected to a PLC that is
located in another building. When you remove the cable from the terminal, you will
loose the protective earth ground of the terminal. Since these 2 buildings can have
different earth grounds, unplugging the cable from the terminal can lead to an
electric shock created by a ground loop (voltage potential difference between two
separate buildings).
DANGER
HAZARD OF ELECTRIC SHOCK DUE TO IMPROPER GROUNDING
z Remove power before installing or maintaining equipment.
z Ensure the equipment is properly grounded to the service entrance of the
building.
Failure to follow these instructions will result in death or serious injury.
