6. When installed in the final configuration, the product must comply with the applicable Safety Standards and

regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory

agencies and inspection authorities to ensure compliance.

7. 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.
