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.
