which it is installed. If necessary, consult with the appropriate regulatory
agencies and inspection authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth
grounds of two or more buildings. If products installed in separate buildings
are interconnected, the voltage potential may cause a hazardous condition.
Consult a qualified electrical consultant to determine whether or not this
phenomenon exists and, if necessary, implement corrective action prior to
interconnecting the products.
9. In addition, if the equipment is to be used with telecommunications circuits,
take the following precautions:
— Never install telephone wiring during a lightning storm.
— Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
— Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
— Use caution when installing or modifying telephone lines.
— Avoid using a telephone (other than a cordless type) during an electrical
storm. There may be a remote risk of electric shock from lightning.
— Do not use the telephone to report a gas leak in the vicinity of the leak.
