two or more buildings. If products installed in separate buildings are 
interconnected, the voltage potential might cause a hazardous condition. Consult

In addition, if the equipment is to be used with telecommunications circuits, take the 
following precautions:
•
Never install telephone wiring during a lightning storm.

has been disconnected at the network interface.
